Weapons for Thoarla?

I unfortunately can't use the classic "plasma gun + mini zooka" on her, and I don't have an ABR. Here's my current setup:



I know, they should be slotted. :c The stardust has obviously been my weapon of choice for most fights. Custom shotgun mostly just gets used for breaking trees instantly, but it's useful up-close against L-size bots. Unfortunately, it's pretty useless against everything else. Is this a reasonable setup for arena, or should I swap the custom shotgun for something else? And if so, what?

To be honest, Thoarla's a sniper, CSG isn't good for it. And if someone gets close, it's your teammates job to support. You got Jupitizer to troll those who get close.

That setup weapon wise is more built for a Baltheon.

Lightning gun from gara Thoarla's AM.
Or another stardust cannon.
