Target Priority
One of the worst things about this mode is target priority, apparently your champions don't know what that means, if a target has the lowest health or the target you're attacking is invulnerable your champion should automatically switch to another target. Instead I have champs that spend 50% of a round attacking targets that can't be killed or worse yet fighting 2 targets and letting the guy with the 5% health kill them while they keep attacking the guy who's at 100% health. FIX THIS!
