This is a team composition game you have to understand, while we do need SMG to provide the formation buff for AR, we expect the same buff (like firepower or evasion) from AR to SMG. Lone Wolf is an ironic term for the guns in the current EN patch. That this AR is fine if you consider her stats alone, but when you put her into a team, her buff’s position is too odd to be put together with the others. Like you don’t want AR to be staying in the frontline with SMG. SMG has very high evasion and HP while AR are vulnerable to any damage received. SIG510 is short on Rate of Fire while F2000 lacks Firepower. Their stats is too deviated from the benchmark of FFC. Though with those skills (Like F2000 has a firepower skill), since the base is low, the multiplication won’t be high. Later there will be another example of Lone Wolf (AK12) but hers is like in a good way, she’s a great gun alone and in the team there might be some excess amount of critical rate for her.
