The antagonist system is a brutal experience, to say the least. If the team can at least stay together, then you may as well not try unless you have a character that can hit with aoes or have long-range capabilities. Anything besides these two save the aid of many mobs leads to being chased and meleed to death. This is just staying together mind you and not any actual coordination. The odds feel stacked against you to a painful degree where in some situations you are doing fine and others you are getting your skull stomped in. To offset this I would propose removing the loss of stigmas when losing, that way the best have more stigmas and the not so good don't rage their minds away. That's just my opinion.
Regarding melee, it's fine as is I just want to know what dictates the outcome of two characters grappling each other. Also why when punching you can track and catch someone dodging, giving them little time to fight back. This happens on and off, it's this inconsistency that irks me more than anything. Besides that everything is fine.
