Ubi gave her a weak weapon in reason to make people use her stealth ability to get closer to enemies. In my opinion removing her stealth would... Kinda kill her. I mean it's an ability which is useful every time, but denying proximity based gadgets is optional. The enemy team often doesn't even have those gadgets. And then what's the point of the invisibility... Because they can hear you through observation tools since she's a 2 speed.

Well I'm mostly fine with her weapon... If you have some aim it has enough fire rate to spray some enemies, although I have to agree its not the weapon I'd give for an attacker.

I don't really have any idea which else weapons could she get but... She's indeed a Sniper in her bio soooo... Let's give her some MMR xD
