Its about time TW had a refresh for raids and add new ones.
Classic should have Blackwing Lair
TBC should move away from BT to SSC
Wotlk should move from Ulduar to Naxx
Cata move from FL to DS
MoP should have ToT
WoD should have blackrock foundary
Legion should have Nighthold
BFA should have BOD
Also need to be refreshed every year instead same old 5 .
Well e.g. I agree with M+ and using old dungeons, just because they are modified for every season and brought up to date to current tool box and ilvl. The same way I have no problem with Horrific visions etc.
From my point of view the problem is content like TW where just a scripted level scaling is used and mostly the same appearances with new Source IDs.
No problem at all if it is modified to current state of the game.
If it is just a prescripted scaling, then in a few xpacs it will be another TW BT, that hardly brings any challenge and exists just for farming stuff and new forum posts requesting replacement of such an instance will appear regularly
Great idea, and I will hijack it to the following:
For each expansion have its 2 longest/largest raids modified for Timewalking, taking alternating turns whenever that expansion is featured as Timewalking.
So from Classic it should alternate between AQ40 and Naxxramas
TBC: BT and Karazhan
WotLK: Ulduar and ICC
Cata: Firelands and Dragon Soul (but take Spine out of it, no way pugs will know how to do it)
MoP: ToT and SoO
WoD: BRF and HFC
Legion: Nighthold and Antorus
BFA: BoD and Nyalotha
SL: SoD and SotFO
DF: Assault on Obsidian Citadel (yes, the bihourly event)
