Not bad, just overshadowed. Especially in TPS.
When I first played BL2, I lived and breathed Maya. Even now I use her a good bit just because she’s good with every weapon type. But she relies on BL2’s gear, and is more “easy” than powerful.
Except in TPS everyone has access cryo, and most character’s best-in-slot grenade is the Quasar.
Most SMGs in TPS either suck, or can’t compare to the stuff other vault hunters are using. The top tier characters use shotguns, and even then there’s snipers and lasers.
The Sandhawk carried the SMG name in BL2, and is part of the reason why I say she’s so reliant on that game’s gear.
I may be wrong, but TPS scales so much more softly than BL2. Cryo also gives a bigger buff than slag, the Avalance allows you to apply cryo in Deception, you can use any gun you want with a blade, etc…
