I think Slaughter as a game type has some potential.

My core concern for the game mode revolves around the Adrenaline System and how it interacts with Battle High and Battle Fever. Adrenaline should not be generated from damage (and kills) done by Limit Breaks as it makes it too easy to overwhelm your opponents with back-to-back Cometeor (72-man) or Raw Destruction (24-man). A coordinated group should be able to push an advantage with these abilities but they should not be able to snowball the game into a one-sided slaughter within a 30-second time frame.

Overall, I feel that the 24-man Slaughter plays out pretty well. I think the that 72-man version could use a bit of a tweak in terms of objectives as there is very little incentive to leave the middle platform. It feels like the intention is that once the first node (+Haste) dies, the teams are supposed to split up to take out the outer objectives (+Damage). The problem is that the second center node (+HP) spawns shortly after, rewarding just as many points as an outer node and giving a large HP boost to counter-act enemy Limit Breaks. As long as you secure this node you are not really disadvantaged in terms of points even if another Grand Company is able to secure two of the outer nodes. In fact, you will largely find yourself at an overwhelming advantage due to the stray kills you are likely to pick up while sitting in the middle, especially if you manage to stack Battle High or Battle Fever on a few members.
