I’d much prefer the old talent trees as well.
The borrowed power systems Blizzard keeps coming up with, and tying you to a max level leveling progression, getting into a class will NOT give you a clear picture as to how the class is when you finally finish your leveling progression. It just muddies the waters.
For example in BfA there was never a talent or a passive that you COULD SEE in your spellbook or talent trees, or if you inspect the set bonuses from the raid through the dungeon journal, that specifically procs an RNG Avenging Wrath for you. Sorry, that was tied to the Essences.
Or similarly, while you could inspect that there is an Azerite Trait that increases Avenging Wrath duration by 5 seconds and has a small AoE component on using Holy Power spells, you never knew that that 5 seconds wasn’t stacking, or when you get it in the first place, as you have to level your necklace AND raid at the same time.
It just muddies the waters and ties people to a leveling experience at the maximum level, which is pretty much always the stupidest design you can come up with, especially in World of Warcraft. Some games do it good like Diablo, PoE, etc, but not WoW. And it can’t be done good in WoW.
Compared to the old system, you could easily check all the talents, all the spells, all the glyphs and all the set bonuses before you leveled up, and when you did, you could access all of them, with the set bonuses being tied into the natural gear progression, making it feel smooth and fun.
When you get max level, you are complete. There isn’t any more leveling to do, there isn’t some insane new passive modifier that you have to grind, no: what you see is what you get.
A lot of people argue for cookie cutter stuff and that 5/5 crit stuff was boring etc.
First of all, cookie cutter isn’t an issue at all? Not to mention that even now we have cookie cutter stuff, except it’s more agressive as the game is tying you to a covenant choice. There will be great builds, there will be bad ones - the old one just happened to give you more flexibility in the regard that you don’t have to regrind an artifact weapon, or a new azerite piece to use 3x Soaring Shield - no, that is something you can choose to talent into.
It also allowed for some goofball builds where you could spec into 2 or more specs at once, again, some powerful, some complete memes, which is once again, fine.
As for the 5/5 crit or 5/5 5% increased damage dealt… I really think Cataclysm improved in this aspect with it’s talents, but I’d honestly argue having the 5 points choice for 5 crit is a lot better as you can directly choose how you want your stat distribution to be on your gear.
For example in Cata, I never went for Critical Strike as Ret, as you could pick up multiple talents that increased your crit chance in a much more nuanced way. You could pick up 12% crit for 2 points on TV and Judgment in the Holy tree, 15% extra crit on Crusader Strike and Word of Glory for 3 points, and 6% extra crit on Hammer of Wrath in the Ret tree + 60sec reduced wings CD for 3 points. You could also choose to double down on your Crit and gear for it, which is something a lot of people did for PvP.
The point I’m really trying to get to is that the old tree gives you a much clearer vision of what your class / spec actually is instead of having some external complicated borrowed power leveling system that muddies the waters.
