I have had issues with the way D2 was implemented from day one. Maybe I played it wrong, maybe I didn't do the right thing, but the whole game seemed to be
1) Complete missions - hit skill wall
2) Grind public events. (usually the walker one on titan)
3) Continue missions - hit skill wall
4) Grind public event.
5) Complete story.
6) Grind public event.
7) Complete Raid.
I haven't got any particular desire to get any gun or armour. I couldn't tell you the name of any single piece of gear I'm using, because I just don't care, I'll get another thing 1 point higher and it will go. The DLC story started out really well, but lost its way and fizzled out a bit.
