I think I can do act 3 inferno, and I don't feel like going through act 2.
I haven't actually played much multiplayer, but I heard it's possible to jump start people to later acts in the same difficulty level? I'd appreciate it if someone can take me directly past siege breaker and hopefully I get it permed so I can keep going back.
They fixed that exploit a while ago, so you'll just have to slog through the canyons, with or without help. I'd help you but I'm not exactly equipped for Act II atm myself; I must've died 200+ times yesterday and I've still to clear two Zoltun Kulle places (and when I say 'clear' I mean run like a headless chicken for the blood/head/other unmentionable that I'm supposed to fetch for this joker). I thought I'd never say this but I miss the Maggot Lair and the False Tombs pretty badly.
Well, I'm a DH too, so there's not much I can do to help (wish there was a way to give your SS to another player). Besides, I got lucky and I'm now at the last cave, and I don't feel like going through them again anytime soon. Sorry to disappoint you though; if you can get through the Zoltun Kulle part, I might be able to help you 'til Belial (maybe join a public game? I've never joined one yet so I don't know if that works out).
Edit: w8, don't you play on the US servers? I'm on EU so I guess if you're on US you'll have to find someone else. I think most public games might be farming games by now, but maybe with some luck you'll find help that way. Come to think of it, I might've tried this myself instead of running through the caves 200 times... But well, that's what Finnish 'sisu' is all about; they say a Finn can go through a gray stone, while others are wise enough to go around it.
