Just a suggestion, could you add a feature that turns off music but leaves in game audio, I like to listen to music while I play so I turn off the sound but I'd rather the "game audio" stayed.
the sniper is so annoying, now maybe it changes, but for me, on the first one, you have a separate click to reload a single shot, and you REALLY need to add crosshairs before you scope in, it's a pain not knowing where you're going to scope in, you see someone, scope in, and your about 10 feet off, then have to move your mouse on really low sensitivity, (even when switched up DPI to 6000 it didn't speed up) and they're gone, it's really anoying, please rate p for developers to see.
Unity is THE most frustrating plugin I've ever used, when you think it works on a particular browser, all of a sudden, it goes on you, I like unity games but I'm going off them because of how inconsistent it is.
If you're going to keep the rent thing, then at least make so that the timer only activates when on the game, instead of the annoying situations like getting a rent for 6 hours in a lockbox just before you're about to log off.
maybe you should add interactive environments, such as a gunning post or possibly vehicles, then you'd need some larger maps and people could choose vehicle games or not.
Now I know in red crucible 2 the game became about vehicles as a result so add very few vehicles per map unless there's a total vehicle mode.
Or maybe not but I hope his gave some ideas anyway, the interactive environment though probably wouldn't change the game too much.
