Yeah, I just stopped caring. I know it feels like it reflects badly on you, but enmity is a team sport in FFXIV, so if they want to be stupid and tank it, they can be stupid and tank it. If it was an accident or if they are smart and stop dps, by all means provoke+hawk it back to you. Otherwise just move onto the next mob and hope they learn for the next pull. Threat positioning is so blatantly obvious in this game they really don't have an excuse.
