Combat ress from crafted item need to be reworked.
Especially as a tank in M+:
- Move on dead body position
- Start casting combat ress and hope for no dmg on the ground
- Combat ress failed ( Knockbacks, character small effect and the worst Polymorph)
If you want to keep fails effect, just remove Polymorph for tanks. You just insta lose aggro and be polymorphed for 4s. If Healer is that dead person, no dispel for you and dps get one tap from boss.
Welcome change will be moving with that cast too. Lets say, if you are in range 5y around dead body, you can move with that cast to prevent not die on frontals or aoe dmg on the ground.
I understand you wont give CR for every Tanks or insta cast on it. But compare to normal CR. There is no Range for safety cast, its not insta cast when you have Holy power/Guardian druid. And there are random fails when you ressing.
