The games average at best. Hit detection desync etc are all absolutely fkd. Especially on PC. On console you get aim assist half recoil and next to no bloom. That's why when you die to a controller player it feels like an aimbot, dead in a frame. Because it basically is. Javelin had a good 2 weeks before the cheat sellers got around it and with respect being free it just makes it easier for cheat makers to get around it. Just make a new account.
