MM Hunter Mage Tower: you could usually get Raest to around 30% by phase 3 back in Legion.
Timewalking Mage Tower: You can’t even get him to 70%.
Frost DK Mage Tower: Back in Legion Xylem’s Frostbolt did less than 15% of your health.
Timewalking Mage Tower: It does more than 20% and you’d be lucky getting past the first Razor Ice.
Also keep in mind that we had an outrageous power creep in Legion that we were able to utilize in the Mage Tower, such as survivability, legion-daries, artifacts. In the 9.1.5 version, everything that isn’t in our spellbook is disabled.
It’s not that the fights are hard, because they’re supposed to be. It’s the fact that the fights are overtuned to the point where it’s basically impossible to do. There’s a difference between difficult and undoable.
