Is there any way to get out of the exotic weapon bounty tier that you are in? I've gotten 4 missives all for the same 3 weapons, thorn, bad juju, and invective, i've already got 2 invectives, 1 bad juju, 1 thorn, and i'm working on Another invective on the Same Character! how can i get it to give me the choice for the other 3 weapons?
