More hotfixes were released tonight that nerfs Halls of Infusion and makes runbacks slightly less painful.
Halls of Infusion Nerfs
These changes make the final area slightly less deadly, and should make runbacks slightly more bearable… however I think many players would like a more traditional checkpoint system in this dungeon.
Crashing Tsunami damage reduced by 20%
Wowhead Note: This looks to reduce the damage of both the waves on the Gauntlet and the final boss.
