I agree that thorn is an annoying weapon, but I don't believe it is OP. Look, most times if me and a thorn user see eachother at mid-long range, my hawkmoon beats them 3 out of 4 times. I imagine some pulses do the same. Closer ranges and things get a bit more dicier, as they always are. The thing is, I think most people complain about thorn because its one of the few weapons you know you are getting hit by, other than vex and maybe hawkmoon. Yeah, I get killed by thorn a lot, I also get killed by snipers, shotties, pulse rifles and the odd AR. Out of all those weapons though, I only really know when I'm getting hit by thorn because of the dot, the rest could be anything. Thorn is annoying, but its not OP. If you get hit by it, run! Don't give them an easy kill. Recover and get to range to make em pay!
