To preface this post, i recognize these devs usually don’t change how items work, or they never have in the past (?). But this item is a huge problem in pvp, and only mediocre in pve.
Why is it an issue?
It allows for the cleric to solo entire teams if he is the last person standing. The usual strategy is to kill him earlier, but sometimes that’s just not possible. With taunts and stealth, it may be impossible to target him. He has infinite sustainability as long as he gets his ability off.
What’s the solution?
This isn’t an easy fix without completely nerfing the weapon or finding a suitable replacement. The core problem will still stand, he is too sustainable due to the instant heal it provides if it procs. Effects like block, which stack, will continue to make him invincible because he can just heal, but this leaves him susceptible to disarm, stuns, dominate and other cc which greatly weaken his ability to heal infinitely with a 3 turn invincibility buff.
My suggestion would be to change the death ward to have either an internal CD of 2 or 3 turns, preventing him from spamming it or change the effect to something such as an AC buff or block effect or regenerate (25%?) to a random ally, while keeping the heal.
