But really if it's a pack of mobs they should just get in the middle and use their biggest AoE threat and it's theirs. PLD has Scorns, WAR can OP in the cone, and DRK has Unleash. DRK has the best AoE threat with A.Drain since we can spit that AoE without being in the center. Just like healers, we tanks also have non-ideal scenarios to cover for. Doesn't mean we like it though.
In reality though, I just click off the extra regen. But obviously best to avoid AoE regen whenever possible, and the ones that do Medica II before a pull really need to wake up and play their job right.
