OK, so you want a Tank to just not learn anything, be mindless, and be even worse off for Duty Finder later when they might just have to press two buttons instead of one. Get out of here. You're taking niche situations and applying them to majority. It's pointless. For every one instance of a poor party with people who can't play their respective roles, we ignore ten that do so properly. Tanking at low level isn't even hard. The stat difference at level 15 sync is marginal and easily overcome by proper technique. If your ideology is that it's too hard to Tank early so we have less tanks, good. I'd prefer that we have ones that at least know what they are doing having learned from level one up.
