There are many games where a class or two don't have "supportive" skills and they are the one who takes the advantage of the ones who have the support buffs and deal the most damage where it's needed.in fact if you all are supportive then you all aren't at your max dps. That's the trade off. Either spend 8hours trying to do something extremely over safely or take 3hrs while still being safe with people who actually have good damage where it counts
