Strictly speaking, theyre quite decent as AR equivalents and I sometimes wonder how SF never won. Honestly they have passable all-round performance.

Practically speaking their skill is awful and you have other options, so raising them is kind of a waste unless you already have lots of everything else

Hot art (Why dont we get their proper portraits Mica? The damned Aegis do), a big gun, decent performance, low cost, no frills. She's a DPS unit that deals damage. Decent Firepower, High Acc,... surprisingly good evasion for a DPS. The skill she gets is pretty much what SWAP Jaegers torture players with. Also punches through some armor.

Good general purpose if you have room in the team.

Her skill is hit or miss (+damage early in the fight, though its a BIG number so it can be worth it) but her big thing is just continuous DPS. Unlike G&K MGs, she never runs out of ammo. Otherwise, quite similar to G&K MGs with basic AP loads. Surprisingly low cost too.

1 downside is she mostly gets replaced by her SWAP version.
