Some guns arent the easiest to obtain and nothing more dissapointing than finally getting that gun just to look and see that the perk are awful. It was a great thing during H.O.W dlc to be able to take a good gun with crappy perks and beable to re-roll and possibly get a good roll instead. A buddy of mine cant get a good roll on the imago lop and he has been trying since the strike was available. Me ive been trying for a full auto tread upon stars but havent been able to get one... and now we have to farm for a skeleton kep to even get a chance at getting the gun in the first place much less get a good roll.
