I can agree that a lot of issues like balancing need to be focused on first but there's still some stuff they could throw up again in the meantime.
-Can bring the STAR LCR's back
-Far Vanguard (The FAR Spearhead is on Armas but it has the reflex sight on the model which I would definitely buy the gun again to get rid of)
-Add the pack exclusive weapons as standalone. ACES Rifle already had this treatment years ago so the rest of the guns like the S1-series / ISSR Wisp, etc may as well have it too.
-4 slot Dolton Fresno, Montane, T-25 (4 slots of the two former aren't even available in F2P either)
-Probably a few other things I forgot about.
Balance is absolutely a priority but there are a few changes Armas could get that wouldn't hurt anything as far as I know.
