Does PeeBee do anything in combat?

I don't use Peebee that much, since she seems underpowered, but I'm going to try her in some of the last priority missions just for fun. I'm using a lot of biotics in my current playthrough, so I can detonate some of her pulls. I might need to respec her to make sure Lifting Shockwave is selected, so I can have another primer.

Drack overall is the best companion in combat (and one of my favorites in general). I've never seen him go down in a fight and many times, he gets more kills that me, or outright killsteals! Plus it's so much fun seeing a badass Krogan charge into battle head-first.

Vetra's disruptor rounds are amazing, but Vetra can be a glass cannon if I don't watch her and make sure she's in cover during a heavy firefight.

Liam's never died on me either, but I just don't bring him along that much ¯\_(ツ)_/¯

Cora's doing better after I respec'ed her, as well.

Jaal seems okay at combat. I mostly brought him along in my first playthrough for all the dialogue. Oh yeah and his Avenger Strike hits really hard, so that's a plus.
