I have 3 Suggestions. 1) There are a few mobs that have insane shield recover times and resistances. I am at level 27 and some of the Wolf Pack Bounty bosses are ridiculously hard to kill and not just by myself. I have a level 32 and a level 30 with me. The same goes with Ursok, The Hated I think his name is. 2) Thorn. Yeah. How about just any Exotic that needs to go through PVP to be obtained. To put is short, TAKE THEM OUT OF PVP. Making people go through PVP to get better weapons is not the smartest thing, as a matter of fact it is the dumbest thing. Most people never go into the PVP part of this game and if they do it is to get one of the Exotics. If you do however want to keep then in PVP make it easier to get the damned things. Collect 500 points of Void Damage in PVP "DUMB" that is 100 kills without dying. I don't know anyone with X/0 KtD. Or even add the option to do somthin else that dosn't involve PVP. Like a Special Strike or make it 1000 or even 2000 Hive Points. Just take the damn thing out of PVP I have been trying for almost 2 weeks now and I have gone above 40 points that is just the highest I have been right now I am at 15 I have died that many time. (Yes I do suck at the pvp, ON THIS GAME). On Black ops 2 I come out with a Positive KtD. 3) Crucible Marks are to hard to get. 3-5 is not enough. something like 6-8 would Work Fine.
