This might be an unpopular opinion, but...
Medic Nerf
In my opinion in late game (Rezakiri and Shroud) Medic +6 is a must.
Considered how fast the meter grows when players are downed and how easy it is for newer and unprepared players to join these 2 fights (resulting in them being downed every couple hits), it is currently essential to revive people with as much health as possible, otherwise if the group isn't specifically formed via chat or discord fights will end up in an endless loop of low players being downed.
Everyone is just going to be abusing the other cell bugs, instead of making different builds, in order to maximise the dmg output and reduce fight time:
Not to mention that Shroud set would become less powerful, considered that only Rage would be the only good ability left.
Otherwise people might just turn to solo play, which would make the lack of medic pointless.
