Finally beat the game last night at level 34 with my Gunzerker. Like the game constantly said, Handsome Jack is a douche. That last boss battle was much better designed than the first
Borderlands. I really loved the sense of scale of that whole battle. It felt like David vs Goliath.
on the other hand, was ridiculously easy; I made quick work of that boss by Gunzerking with my strongest shotgun and the Inspiring Fibber (which is a great gun to get on Normal from "I Want To Be a Real Boy"). I'm sure if I max out the Pistol skill, that gun will easily become my go-to gun until I start TVHM.
I too have the skill tree tuned to staying in Gunzerker mode longer for every kill, but it's still been a very slow progress developing the tree. I think I might start
Torgue's Campaign of Carnage on Normal as opposed to saving it for TVHM (it's the only DLC I have since I got it for free).
Since I beat the game, I'm willing to buddy up with folks. I'm on the 360 version; my GT is Johan El Fuerte. I'll be sure to switch my network settings to invite as opposed to friends. I have a very few amount of quests left to do including You. Will. Die. Seriously. which will definitely have to wait until TVHM before I even I even think about taking it on.
