Well my fusion rifle exotic bounty wants me to kill 200 Nightfall enemies :( At least I assume it's just kill 200 as nothing I have killed so far has given more than 1 credit towards it, even majors (yellow health enemies) though I havn't killed any named enemies or bosses with it as I've just been killing enemies in the early areas solo. It's not... hard... but it's going to take aaaages.
