Did I say you were min/maxing? My point was that pure tanks aren't viable, and using twiner builds, for everybody in your party, is the best way to get engagements to stick (or rather, keeping mobs from spamming disengagement abilities to race right for your back line). Not an infallible way, but the best. Engagements aren't meant to make mobs stick so much as giving font liners an extra attack.
