I didn't spend a lot of time shooting things in Borderlands, once I got enough talent points.
Nobody else has a badass sword in BL2, and I'm guessing no one else will be quite as potentially melee-oriented as Zer0.
As a plus, he reminds me a little of me. Skinny, frail-looking, doesn't talk much, carries stick everywhere he possibly can.
I just seem to like the tanky / bulky characters. Just looked Salvador up, turns out he doesn't duplicate his current weapon, but rather he pulls the next weapon in his inventory down into his hand.
He has a couple of neat talents too, but I'll see what he's really like when it comes out.
How late did you stay in the stream? I had to go to bed fairly early. He was playing some presidential campaign game when I left for work this morning.
