I’ve scanned all the Classic patches from 1.1 to 1.12, and compiled all the nerfs and major changes made to instance difficulty and overall gameplay and itemisation. I left out all the changes made to Classes, talents trees, professions and in-depth item changes.
Patch 1.1 and 1.2 - Didn’t bring major changes in terms of gameplay or progression to the game, only some minor class tweaks. Maraudon added to the game.
Patch 1.3
This were changes to raid/dungeons difficulties started to happen.
New dungeon Dire Maul ? 5 man cap
New world bosses - Azuregos, and Lord Kazzak
MC teleport quest - Attunement to the Core
New dungeons player caps ? All dungeons and raids were previously 40man cap, with the new patch they’re now the following, Ony/MC 40man, UBRS/LBRS 15man, Diremaul 5 man, every other dungeon 10man. Several dungeons will be re-examined for balancing in light of this change.
Nerfs to dungeons and raids (and some loot changes) ?
Lengthened the respawn time of many of the creatures in Ragefire Chasm, Gnomeregan, Uldaman, Razorfen Downs, Scholomance, and Stratholme.
Onyxia
Onyxia’s fireballs will no longer result in a confuse effect (Engulfing Flames). The impact damage of these fireballs has been slightly increased to compensate for the loss of the damage over time.
Increased the delay before Onyxia will try to tail sweep.
Stratholme
Baroness Anastasi in Stratholme will now leave the possessed target when the target is below 50% health, instead of 30%. She will also cast Possession slightly less often.
Roaming Gargoyles will be set to a 30-minute respawn.
Roaming Shades set to 15-30 minute respawn (previously 5-15).
Patchwork Horrors set to 15-30 minute respawn (previously 6-10).
Overall respawn in the entire dungeon made longer.
Crimson Conjurers will no longer roam in pairs.
Crimson Conjurers can now only have a max of two “pets” at one time.
Scholomance
Lengthened the overall respawn of the dungeon.
Risen Aberration health and damage reduced.
Reduced the duration of Dark Plague from three minutes to 90 seconds.
The creature spell, Call of the Grave, has had its damage reduced by half.
Blackrock Spire
Spire Spiders now only summon four Spire Spiderlings instead of five.
Health and damage on these Spire Spiderlings has been reduced.
Crystallize has been reduced from eight seconds to six seconds.
Maraudon
Noxxion encounter made easier for groups lacking area of effect damage.

Toned down the Zigguraut event.
Toned down the Antu’sul event.
Scarabs will no longer flee when at low health.
Patch 1.4
After patch 1.3 changed the player caps, many dungeons were nerfed and their loot tables received major buffs making Raids such as Ony and MC easier due to better gear stats.
Major change to the 5 seconds rule and how healer play in general ? “Mana regeneration is now disrupted when a spell has completed casting rather than at the start of casting. It will resume normally five seconds after the last spell cast. This change increases the total time spent regenerating mana and therefore increases the total contribution from Spirit for mana-based classes.” This allowed a playstyle of pre-casting heals and interrupting them when the tank avoids dmg, by blocking parrying or dodging, making it much easier to save mana while keeping the tank always full HP.
Nerfs to dungeons and raids ?
Bael’Gar, Lord Incendius, and Golem Lord Argelmach are now lower level than previously.
The Baroness Anastari encounter has been changed. Players who become unpossessed will now have full health, and after the Baroness unpossesses a player there will be a much longer cooldown before she can cast possess again.
Lava Surgers no longer respawn once you kill Garr.
Ragnaros now stays up 2 hours rather than 1 after being summoned.
The Golemagg and Shazzrah encounters in the Molten Core has undergone some changes. (nothing specified in the patch notes, but probably nerds aswell)
Major itemisation buffs to all high level dungeons (many blue rare items were added to the game making the content a lot more trivial) ?
Scholomance Itemization
20 new Rare items have been added to Scholomance.
Several Uncommon items have been upgraded to Rare quality.
Rattlegore, Jandice Barov, and Lord Alexei Barov will now always drop at least one Rare item.
Ras Frostwhisper will always drop at least two Rare items.
Stratholme Itemization
26 new Rare items have been added to Stratholme.
Several Uncommon items have been upgraded to Rare quality.
Archivist Galford, Baroness Anastasi, Nerub’enkan, and Maleki the Pallid will now always drop at least one Rare item.
Raid Itemization
Onyxia, Azuregos, Lord Kazzak, and all Molten Core boss creatures have all received some new items on their loot tables.
Onyxia will once again drop two upper tier class set helms.
Most of the non-class set items that dropped from Molten Core and Onyxia have had their effective levels increased, resulting in higher DPS weapons, and/or better stats and effects.
Players who defeat the Majordomo Executus encounter will now be rewarded with new epic items. This reward will only be granted the first time the encounter is defeated during the 6 day lifespan of a Molten Core instance.
The loot tables for some of the Molten Core bosses have been improved so they drop an additional epic item per kill.
World bosses such as Onyxia, Azuregos, and Lord Kazzak will no longer drop random blue items of a level lower than 50 (buff because it will drop high level items instead).
Prior to this patch, Molten Core boss creatures could drop items from one of two different tiered sets for every character class. The loot tables have been changed so Molten Core bosses will now only drop items from the lower tier class sets. However, some of the items from those sets were not previously dropping in Molten Core. These missing class set items will now drop in Molten Core, allowing players to complete their lower tier class sets. The higher tier class set pieces that once dropped in Molten Core will be found once again in Blackwing Lair, the next raiding zone scheduled for release in a future patch (this only happened in US servers, because EU was release later and didn’t have acces to tier 2 sets on MC).
Future patches will include even more item rewards for these raid encounters, as well as improvements to the statistics, effects, and set bonuses for both tiers of the raid armor sets.
Patch 1.5
Battlegrounds were introduced and Ragnaros had a minor nerf, new items.
Molten Core

Currently there are a handful for each class which can be found scattered throughout Blackrock Depths, Blackrock Spire, Dire Maul, Scholomance, Stratholme, and The Temple of Ahn’Qiraj. We hope that you enjoy the first round of available relics and we will continue to add more in future patches.
Many items in Blackrock Depths, Stratholme, Scholomance, and Blackrock Spire have been re-evaluated and adjusted to make them more appealing. In addition several new items have been added to all of these instances.
The following item sets have had their set bonuses adjusted/increased: Valor, Magister’s, Lightforge, Shadowcraft, Dreadmist, Devout, Wildheart, Beaststalker, and Elements.
The locations of some of the waist, wrist, and hand slot pieces of the dungeon armor sets have been moved from their old creatures, including the [Lightforge Gauntlets] and the [Magister’s Boots]. Additional creature types can now drop many of the previously difficult to obtain armor pieces.
