All thorn owners know how painful the bounty was. Especially the crucible part. I'm a fairly calm gamer, not casual, just calm. I found myself screaming at my television because of how frustrated I was. And it doesn't get any easier in the next parts. For the trouble of the bounty, the newfound power of thorn certainly is fair. Secondly, vex mytho is the "hardest weapon to get." Damn right it's overpowered.
