I believe that I have read a post somewhere where someone wasn't getting any achievements for NiM EV. I'll look for that post and add it to the known issues if there are other people having the problem.
I'm about done with Line Bisector, though just discovered that it can be cheesed. The things that are going to be the bottleneck for 100% in events, though, are probably the slug/wampa kills since it's harder to get/organize groups for those, while competing with the opposite faction for the bosses.
And on a side note, I wish more people would queue with their Jawas. I'm only at 20something for that achievement.
It's specifically the last 3 bosses of NiM EV 8M got credit for the first 2 and the 2 hour title. And yeah I have 40K+ WZ kills and still at 92
