Well she basically has the lowest RoF with the highest damage out of ARs, so maybe use tanks that can boost her RoF, like RO635, Vector, or SR-3MP. I'd say she'd be perfect in a DPS focused group based around SR-3MP as your main tank, as she buffs accuracy which is also SR's weakness.
RFB | Vector
Buffer | SR-3MP
Note that I do not actually have her yet; I'm basing all this on her stat line, so take it as you will. Also your main echelon may be lacking a bit of damage from G36C as your offtank. If you can, Vector would be perfect there.
