OP claims it's not about DPS nerf, but about spell rotation, and makes silly claims about standing around twiddling thumbs for 2 seconds, and refuses to consider simply adding another spell to their rotation, with the even more nonsensical statement that casting a non-Fire spell somehow nerfs themselves. If there's a loss of brain mass, I don't think it's the "community".
(Though I don't think the OP is actually that dumb, either. I suspect they actually simply wanted their higher DPS back, didn't want to admit that, and used the spell rotation nonsense as an excuse. And now don't want to admit that their original excuse is bogus and come clean about their actual motivation.)
