I just started playing this game the other day, but I do have to agree with the antagonist system being kind of broken at the moment. I don't know if this changes later on, but early level it feels like I have no chances of winning. Between getting matched against players that are 2-3 times my level, getting spawn camped, having no time limit for some of these missions, and the fact that the Raiders can just hide and wait for their respawns to come back up, the Antagonist is almost guaranteed to lose. Which means you get no rewards out of it. I literally spent 51 minutes in the Hanging By A Thread mission. On the last phase, the Raiders simple stayed in spawn almost the entire time. There as nothing I could've done about it. Then, when I inevitably lost, even though I killed them almost 50 times and we spent 51 minutes in that match, I only got 2200 G. I could get more by splitting Raiders G rewards 4-way!  I really love the idea of the antagonist, but in reality, there is no reason to play it.

Anyways, since this is a suggestion post, here is mine. Have characters that are specific to their roles (Raiders/Antagonist). Characters like Schneider, Ginebra, and Dr. Kuzman, really have no place in being Raiders. And the reasons that are given for Ginebra and Kuzman feel like cop outs. I think it would make more sense to have these characters be Antagonist only, and that will allow them to be balanced as such. This would make it so that we could actually have Antagonist that are strong and fun to play.

Also, having a time limit for the Raiders to complete objectives wouldn't hurt. It would counter the spawn hiding that always happens in missions like Hanging By A Thread.
