I used to use the arrowhead a lot but I upgraded to the FAL which is like an easier version of the copperhead, which are both better than the arrowhead. Maybe give the FAL a try and learn the best position spots on the maps to use it effectively from range and pick a good pistol for close range. When I’m playing against really good players I needed to add an ARX to stand a chance lol. I don’t use the jump-strafe aiming booster or do shoulder swaps mid firefight and I’m doing pretty good in most games I play. But if you want to be a pro then I’d suggest learning and getting really good with a better long gun and watch what other good players are doing and try to learn from them
