This problem is gone in WoW because 98% of all attacks do not have added threat like FF14's tanks do. If we want to tank, then we get into tank stance, which gives us massive threat boost for anything we do. So if you tried to tank without tank stance, you're going to get kicked.
. . . . .FF14 Should never have the tank stances be late in the game, and most importantly have attacks that deal extra threat which enables any of us to get away with it.
