I rarely use thorn and I dont think its op. I guarantee ive killed more thorn users than have killed me during IB. You just need to learn how to approach it. Theres not many skilled thorn uses out there and when I do come across a skilled player red death beats them 9/10 times. If you dont have a red death use a scout rifle and beat them at range no scout rifle get a last word and beat them close up. The gun is not the problem your lack of ability is the issue learn how to counter it and you will no longer fear it.
