Putting a limit on snipers won’t fix the problem; it’ll just make life harder for the ones who actually play the role properly. A good recon isn’t just lying in a bush. They’re marking targets, helping disable armor by painting and spotting vehicles, clearing angles you can’t see while you’re rushing in and helping the team move up.
The problem isn’t the number of snipers; it’s the players who don’t know how to play the role and can’t hit their shots and you’ll find those in every class. I’ve got over 11,500 kills so far in total and sit around a 6.7 K/D and that’s after grinding through every weapon and almost every class challenge. The only thing I’ve got left is the engineer task with 6,000 repairs to go and i'm stuck and struggling on that one its a hard to hit 3,000 never mind 6,000. The game’s just a lot smoother and easier to get kills now. in previous titles I sat around a 1.8–2.0 K/D. The issue isn’t the class needing a limit, it’s that most players are just grinding challenges or going for super long shots instead of playing aggressively and supporting the squad take the objective.
