You will most likely get ganked in STV, I'd say stick to desolace. Then go to Badlands around 37 or 38.

Nah. People try and jump me, and I rape the shit out of them. Sacrifice on VW (1000 damage absorbing shield for 30 seconds) + summon succubus > level 38 rogue, who ran like a fucking bitch away from me.
STV will get you to 50+, so you won't be running into just 30s
