I didn’t include it in the patch notes (although probably should have), but Tank Buster attacks (including the ones in the new Raid) were balanced around this change as well as the Paladin’s new move and now have longer time periods between attacks.
This change was more about boss mechanics such as tank busters and tank swap mechanics, not about healers (the amount of guaranteed raid-wide damage in the Raid will contribute more to them being required).
But yeah if it makes some pulls impossible now let us know and we can look into addressing that. It’s not our intent to make anything impossible, but it is our intent to try and balance the Paladin and Warrior’s ability to tank some of the mechanics in the Raid which is what drove that change the most.
