I have a suggestion for damage shields in certain zones:
Cazic Thule
Icewell Keep
Is it possible to flag the zone so you cannot cast a damage shield while in these zones?
What is happening in game is you have a multitude of Low total Hit Point mobs, that easily drop below 95% from a damage shield, and summon you into walls, floors, and anywhere you can get stuck and unable to gate. Yes we have the /rewind command but that does not always work.
