If you're looking for an 8s Grenadier, well, she was always a very strong choice, and now she's pretty much almost the default one for most circumstances by sheer stats and having the 2 accessory slots. Improved Grenade performance (not that most enemies will notice) and bonus MIRVs on top of that. She does get bonuses with M4, but due to the fact M4's marks affect her targeting (and potentially are buggy with her MIRVs), using her with M4 is not always ideal.

Aside from that, it's the same old SOP, but with a unique equipment (thats pretty much just an improved Eotech) and bigger numbers.
