Ok, so she isn't actually bad. She does, however, have a stupidly long skill like a JK cramming for an entrance exam, most of which is largely irrelevant because all you care about is her damage output.

Which I guess is kind of alright.

Her skill has a good initial cooldown, and she's actually better than most ARs, but she won't usurp the position of the top ARs. A good pick for your B-team.

She's basically AUG, but without the random fire mechanic. Which makes sense because she has an AUG. This logic doesn't work for any of the other girls, but shush.

If you'd like an evaluation of AUG to get an idea of how good Angelica is, here's AUG's article.

Actually hits RoF cap at SL10 without external buffs, but she's a 3* and we're drowning in 4 and 5* RoF-selfbuffing ARs that do the same much better (AR-15 even unmodded and all the 5* ones) or just bypass RoF cap altogether (SAR-21, AUG).

FWIW, better than OTs-12 even if the latter has her unique equip, but we have so many RoF ARs that even nodupers shouldn't have to bother with either.

"Are you THAT short on ARs or need cheap equipment that badly?"

You get much better ARs from story events, and there's only so much that you actually need. If you need a cheap AR and already have FNC though I guess she can be useful.

Her exclusive, while it does give her more strength, doesn't let her outperform many 4* ARs.
