A small suggestion for rocket balance; make the 3R8 something like a 3R6. Smaller rockets to compensate for having more of them. In the future a 3R8 might be more balanced with a progression system (make it a late game unlock or really expensive) but right now it's either the normal R8s are kinda bad because they're too weak for only having two rockets, or the 3R8 is too strong because rockets slap hard and you get 8 of them. Since MGs and autocannons aren't that good right now, you aren't really losing anything by dropping them for space for the rockets. Buffing those could also help a little with balance.
It's also fine if you'd rather keep rockets on the stun side over the damage side since they're dumbfire and more spammable but ATGMs definitely should be hurting more.
As a note, I haven't had the time to try out the rc3 or rc4 yet if you've changed them there.
