what your talking about is the old "elitist" mentality..and your better off playing your summoner and not getting sucked into that mindset. Are you or aren't you having fun playing summoner? That's the only test in my book. Whether or not you have 100%tricked out summoner, or follow the very cookie cutter formula of any job.
I've been in this game since day one of American release and sure I can follow the forums "suggestions" but I have even more fun playing quirky job combos that people tend to overlook whether they are bad or good.
I'm not going for some award for most clone-playing skill. And trolls don't necessarily stay in the forums they play FFXI as well.
