I’ve legit never even see what the Incinerate enchantment looks like, it’s so bad. Though I haven’t seen it myself I’ve heard people talk about how most of the time it would just spawn in a corner and breathe fire on the wall for the entire duration.
I think the only real fix for Incinerate, aside from fixing all the broken glyphs and mechanics associated with Burning Damage, is to allow moving while channeling it. I can’t think of any reason not to and have never seen any of the devs articulate why not being able to cast/channel on the move is the status quo. Even most MMOs (with the notable exception of WoW) no longer have those restrictions and almost no other A-RPGs. It’s just an outdated concept, if it ever made sense to begin with.
