I'm pretty certain it will be worth it, given the dlc from the first game.
got BL2 preordered, cant wait
and yes , i find most people are frustrated because they dont know how to build. you can do anything and get through normal-hell but inferno requires you to understand how to max stuff. and how damage is calculated, its quite a bit of fun once you understand it, and theyve made it easier too.
but yeah i sorta just kept playing with no goal trying to max stuff out and ended up with more gold than i have use for
damn nice, new diablo patch is making inferno easier (yet again) but introducing the old "/players 8" skill from diablo 2. its also gonna have uber bosses return with apperently "awesome rewards".
given another year and several more patches it should be changed all the way back to D2 XD
