" Casters have slightly too many instant cast spells, especially healers that can keep themselves alive without ever using a spell with a cast time. "
I only ever played Holy paladin, and Mistweaver monk. The first one is a spec where you're always casting (except a very few things, like ef but it cannot save your life by itself if you're focused), and the 2nd one where you're channeling except for a few things, the most OP being the " orbs spam " when you're hardly trained. I don't know much about the other healers gameplay. Who's really concerned about that future change, and is it so exagerrated ? I understand the " instant " concept might be a clear advantage in a fight (no interrupt), but are some healers classes so much based on instants that you nearly never have the opportunity to interrupt them ?
