I finished the Beta with 2 Lone wolf characters and it was fairly challenging - reducing recovery AP by 1 does seem a bit harsh and the HP nerf as well; although I don't think dropping the HP from 80% to 60% would make a huge difference seeing as the +HP items have supposedly been improved (haven't played since the fix). I'll have to try this out during release as I had a blast with 2 LW characters and my plan is to play co-op with each of us going LW.
