There is no functional difference to me. I see what I encounter. And I see a lot of prideful players who aren't as good as they could be.

Not even saying I/people I know are the best. I know we're not. But we care about self-improvement and take criticism. Or otherwise put our own time/effort into learning and applying The Rotations, be that from guides or other people we know to be good.

I offer to help any wayward DPS I see in roulettes, but it is very rare that they take my advice. Often they don't have key skills even on their hotbar (DRGs lacking Heavy Thrust, BLMs lacking Fire 1).
