I tested Shard of Hatred with the tier 3 that gives +50% movement speed but reduces 10% of movement speed for each mob close to you.
I thought it would work like Stone Gauntlet and Ignore Pain would solve the problem but it dosent work.
This was supposed to work like this or this is a bug?
It depends on how blizzard intends the drawback to work. If it is considered a CC then it is a bug. It could also be that they consider it a debuff and ignore pain does not affect debuffs.
Ok, so i will write a post in the PTR feedback to try clarify this.
