Yeah I'll admit it's daunting, but that's a good thing. You can't just change the rules to accommodate your inability simply because you want it. How unfair is that to those who worked hard to get it? The weapon itself looses its prestige if that happens and that's stupid. However I'd suggest to try it during the next iron banner, that's how I got the thorn when all I had was a void shotgun. During the banner the percentage of diehard PVP players lowers significantly, simply because a lot of PVE players venture out to acquire Lord Saladin's goodies. Also check if your opposing team is in a fire team together (3 or more), if they are go to orbit and load again.
