If your enjoying your gunslinger and have familiarized yourself with your skills and CC then keep with it, but its all situational. With other classes having advantages youre going to have to learn how to adapt, find your hotspots, Assist/Focus targets (Crucial), and use your roots/knocks to your teams advantage(Not just to your advantage). For me nothing is funner than teamwork and completing/defending objectives, doesnt matter what class I play. Right when you get to 50, no matter what class you are, you're going to get ROLstomped until you get your expertise up.
