Tokyo Arsenal 100: Wait, It's Belt-Fed?

Thompsons have very little difference in damage compared to the STG, aside from a higher rate of fire. Wouldn’t that be too powerful for a BR4? I say this because it’s already somewhat unfair to have to face that at BR3. Just look at those PPDs and PPSHs with drum magazines that were BR5 but are now BR4 simply because there are more assault rifles. Unless there are adjustments to the matchmaking, lowering weapon BRs won’t solve anything. Japan is simply pointless in this regard; practically no weapon is useful at BR5 so far except for the Type Hei automatic. Unless they specifically increase the damage of the Tokyo Arsenal and I’m referring only to this weapon, not the others in 8mm Nambu SMGs
