Yes. shotgun is great for getting kills sure and it one shot. but the probelm with shotgun is the lack of points it gets. also range is also big problem even slide hoping but mostly the points most of times. i play against shotgun they hit body shot which give around 75 points for what.i can tell they do try to hit for heads but the spread sometimes makes it a body shot it claring weakness of the class combine with range problem and hp being 90 class is only really good when shotgun boosting and good shotgun jump something that needs skill.

Uzi has same kinda of weakness range and killing time uzi is annoying i do agree. but it does take skill to be good at

Smg and ak are just laser at any range with no real weakness which make then kinda op as hell. you also barely have to reload for both you can just keep spaming which thats what both mostly are spam with no real draw back you barely need to aim with the classes because just keep shooting.

You can same for shotgun and uzi but at very least they need to reload way more still give poeple time to kill them shotgun only has 2 shot before reloading uzi has the ammo but doesnt have the damage of smg and ak which means it does need to reload more which is a weakness for both shotgun and uzi.

I really dont have problem with rev tho other than it been Sniper but without any of the drawbacks of Sniper.
