So I stayed up for Xur and checked him out. Managed to upgrade thorn... at a semi big cost. Xur required me to hand him 1 exotic shard, old thorn, and over 7000 glimmer to get the new one... and it's exact same except for damage output. I'm kinda upset that bungie didn't just updated our exotics right off the bat so now we gotta breakdown exotics for a shard or buy one then fork out a bit more glimmer just for a damage boost.. There is a few weapons up for upgrade mostly hand cannons and some armor. Check him out and tell me what you think.
