Bummer, I seem to get the Vex almost every other time on Atheon. Thorn bounty didn't take me long, but I had the Vex before I had the chance for the bounty. And the Vex is still easier to use in PVP than Thorn. Thorn is better for some maps though, and a skilled Thorn user will likely beat a Vex user 1v1. I just hate all the complaining over weapons being too powerful. If someone kills you over and over with any weapon, they might just be better than you.
