Guild Wars 2

I will drop from any group that doesn’t use any strategy — simple as that. If someone dies, fine, sometimes is inevitable. Just waypoint your way back into the fight. But when you see a blue train of brainless dots running back, over and over without regrouping and trying to one-man tank a boss, the challenge is gone.

I’ve encountered this a few times while fighting enemies underwater. Once they hit certain HP level, they will swim away, become invulnerable and lose aggression.
