I think it's worth repeating that the AoE fire arrow / bomb / acid spit spam from enemies really messes up a lot of spells. In addition to just being generally really annoying when it's everywhere, constantly.

I've stopped using Concentration spells almost completely. You're just constantly rolling for concentration and usually these spells end before they do anything. The fact that Prone also (incorrectly) cancels Concentration is the final nail in the coffin. And the fact that enemies tend to jump directly to your spellcasters and tanks are unable to actually threaten them properly.

Because of the fire spam spells like Web and Grease also can't do their job. Every time I try these spells for crowd control fire appears and burns them away.

Can we cut back on the AoE spam and fix the Prone condition please?
