Loot in this game can go to hell. I get a exotic weapon bounty, but who knows what weapon I can get, so I start one with the warlock, at the last step to hand it in I check the mail cause I have a reward for a new rep level. Open it up, its a legendary shotgun, great, just as I am about to hand in the exotic bounty for a shotgun....the real kicker, I fucking hate shotguns and don't use them.
Shit like this is going to make me and a lot of other people quit. Randomness is good, but you also need to give people some incentive. This kind of randomness puts people off. MMO's have learned this already, thats why Blizzard lets people trade in a piece off a boss for a specific item you want when it comes to tier pieces.
