And your manners are akin to that of a kindergartener, if not worse. EDIT: There doesn't need to be any logic behind Bungie's decision not to upgrade the Vex. It's their game. Just because you don't want to have to work to get better guns doesn't mean that that's the way it should be. "Waah, I can't be bothered to get a new gun. I got a Vex once so now I should be OP because I completed an old challenge." Jesus Christ, kids these days, so entitled. *Mute*
