The problem I find with the change is that the new debuff effect of Viking Funeral isn't useful in its current state. It needs to be at least 10% per stack, and last 5-7 seconds. A 5% defense debuff per stack that only lasts 2-3 seconds doesn't help anyone. Good idea, but very poor execution on their part. And its interaction with Solar Grenade is rather odd. It only activates on the initial impact of the grenade when tossed, and doesn't apply at all after that, even if an enemy that wasn't hit by it previously walks through it. The continuous damage from the Grenade isn't affected at all by the defense debuff either. Only the initial impact is affected. They really need to fix that.
