I've read this post a couple of times and I still have no idea what you're saying. You actively choose to do less DPS due to some philosophical objection to killing more than one mob at a time? I don't see how this contributes to the discussion at all.

Generally speaking, I'd rather do direct damage and have those numbers consistently show up as my top 3 abilities than see an AoE ability take one of those slots. If your DPS needs an AoE crutch to remain competitive, you are letting the game play the class for you.
