Slaughter in its current state is still a broken mess. There are several issues, but two major ones stick out.

Cometeor is still far too overpowered. Even after the nerf, a group of casters can still dominate any Slaughter round by stacking their cometeors. When 6 cometeors go off at the same time, anyone in the spread is dead and there is zero defense against it. Any easy fix would be to put a buff up on any player that is hit with a limit break that grants a 5 second immunity to additional limit break damage.
