I've spent the last few days re-learning the mechanics and whatnot, toying with different builds and all that fun stuff (Ranger/Assassin is fun stuff). I'm midway through each campaign, looks like I hit some missions that were tough and branched off to do other things more than once. 

I'm only at 6/30, so I have a long way to go, and I'm still a nub when it comes to grouping/farming etc… If anyone else is in the same boat hit me up and we can tackle some of this stuff.

Sounds like the same wall I kept hitting, that's when I usually work on a new build instead of finishing off chains. I also just discovered I was missing a TON of attribute points since I never did the final quests for those (2 easy quests get you 30 points). 

Right now I have max armor, and max weapons, just need to get the right mods on it all and I'll be good to go I think. 

10/30 now, I keep getting sidetracked trying out different builds, I'll see one I want to try, then have to find someone with the appropriate weapon to buy, then go buy/capture the skills depending on what they are, next thing I know 2 hours have gone by and I'm still where I started, but with a new build to learn too.
