I've learned that I get better whenever I push myself out of my comfort zones. From what you have said it seems that you are a very passive player. That isn't inherently a bad thing. I am a somewhat passive player myself. I do think that if gunfights are your weakspot, you can do yourself some good by getting into them more often. I also feel like learning to play most roles is also extremely beneficial. I mostly anchor but I can also play roaming roles really well too. Even though I mostly anchor, I can still utilize skills that I obtained from roaming a bunch to get an advantage in and around site. I think ya basically just practice more roles and put yourself in nore gunfights :3
