Pretty sure it isn't job based, but player based.
Like I want Summoner to be a jack of all trades, not master of anything, just good enough at spirits, rages, wards. But you'll still find a bunch of people that just want Summoner to be the best spike damage for no hate job.
I'm still not sure why, but almost all people playing a standard melee job only want to do damage. I guess the simple truth is that nobody wants strategy involved. Just engage, drink coffee, WS play. Which is a shame, since this game could be plenty fun if we needed another job than WAR in it.
