But what you are saying is not inline with what he is saying at all. He said affli is bad at low levels because things die too fast for DoTs to be effective. If things dying too fast before you can even put a single SoC on them, this means your group is already way out geared for the content you currently doing. Which also means you are either getting boosted or you have over geared ppl in your group that just mowing down things for you anyway.
This has nothing to do with being an elitist or whatever. I don't know how you reach to that conclusion. When you are in a group with equally geared ppl with the appropriate m+ level, things won't be dying too fast therefore your dots will be doing their job. You can't blame the spec if you are doing +5s with 960 ilvled ppl and complain that things dying too fast.
