Spitfire is not op, you're just toxic
Spitfire is fine. There are many other much more important things to fix in this game. The spitfire was popular and that's the only reason people hate it. Every season the streamers pick a new gun to claim is imbalanced and every season they are wrong. Form your own opinions. If you're being shot at, put some cover in front of you. This game is not that hard and some of you act like if you're not constantly stomping then it's unfair somehow. There are many imbalances in this game but it is not an issue with guns. The bow needed fixing because it is silent and worked better than actual snipers. It's still does more damage and travels faster than the longbow which is likely firing a huge bullet. (Before nerf it was a super sentinel. Why use the sentinel when the bow makes it obsolete? THAT is the essence of gun balance. Every gun needs a place in the sandbox or it is useless and must not make other guns obsolete or it is imbalanced.) There are no other guns that the spitfire makes obsolete. The flatline would be the closest but even then, better movement, better non ADS spread, still 16 damage, reloads faster, better in close combat.
The R99 can fire 10 shots at around 12 dmg each in the time it takes the spitfire to fire 3 or 4 shots. Not only that but your strafe speed is slower with the spitfire. More time firing does not make it deadlier. R99 reloads quickly while the spitfire reloads very slowly. Every weapon has a pro and a con and works best in different situations. Spitfire was never overpowered, you're just salty that it's being used more and you can't rush in by yourself like you used to. This is a TEAM game, not a tryhard sweaty "look at me" game. If anything, people who rush in and the people complaining about it are the people who caused it's popularity to rise as people found that it cancels sweaty playing. Play smarter. That's the counter. Instant gratification is not a mistress worth chasing.
Quit complaining about stuff simply because it's popular to complain about them. You're losing because YOU are bad/out of position/overextending. Not because a gun can shoot.
Also do not conflate normal gameplay with aimbots. If you're being lasered down by a spitfire, it's not that the gun is broken, it's more likely the enemy is cheating. Report them appropriately. Too many people seem to be under the impression that cheating doesn't happen.
