The reality is that the majority of runs are just "say hello, pull w2w, say tfyp and leave" and they run smoothly or with very minor hiccups and the majority of players is competent enough to do just that. There's no need to paint me as some hardcore, min maxed obssesed person because my profile is public and you can see I don't even do Extreme Trials.

If you suck so much that you can't even keep aggro or deal a single damage spell as a healer you can indeed as you say ask your FC to help you as well.
Well this thread was made by such a person so I don't even know why you're trying to argue with me at this point. You're just getting defensive for no reason since we agree!?
