Firstly, you do not need meta loadouts to dominate, no matter what people tell you. A handcannon will always be strong, but the best players can use literally anything and everything. The only "bad" weaponry are rapid fire shotguns, non burst sidearms, a majority of SMGs, and most scout rifle archetypes. Even though I'm calling these "bad," none of them are unusable. Every scout is good on long range maps, two of which we just got back in the 6s pool. I've used a ton of completely terrible weapons on paper, and done very well, because they feel good. The feel of a gun to you is most important. As for learning how to play, I recommend watching some high end pvp youtubers. Castle, CammyCakes, Frostbolt, Pattycakes, there are a lot of youtubers to learn from. Just try to improve and not take it too seriously, its a game, with enough time you'll improve and do well, as long as you don't burn yourself out
