Wow, just looked again and my bow is the 4th highest dps for any crossbow with reduced level requirement of at least 12.
It's this, by the way:
Act 2 is a big jump, yes, but honestly it's not too bad at all. My monk can now tank everything in Act 2 with ease. I just helped someone today with Belial and it was a joke. I took his punches straight on. Didn't have to move for anything except that green stuff that fills up the entire screen. The other parts of that fight were easy as hell, too. You can get there.
It's really Act 3, I think that gets kind of BS. There are too many spikes in Act 3. I can do a ton of stuff with ease, but then one thing comes in and just rapes. For example, I was tanking like 10+ things in that one area past the bridge all at once. I was doing fine, and my life wasn't really going anywhere. 1 fucking Pestilence guy comes over and I'm fucked. You can't dodge that shit. And I'm talking fucked as in dead in a matter of a second if I stick even near it. And that's with a barbarian's shout bringing me to like 1300+ resists. Those flying dragon bastards? Yeah they're annoying as hell. Get an elite with one of those and just fuck it. I'm not going to try and chase them back and forth. I'll hit the enrage timer every freaking time. Soul rippers in the keep? Jesus... I can tank some of them, but give them something like molten and you're just raped in seconds. Meanwhile, again, all the normal groups are pretty simple...
