I've primarily scoped in this closed beta and can say that yes, snipers need a bit of tweaking but they're no where near a problem as everyone thinks they are. Lowering the accuracy while you're getting shot will make snipers near useless considering how arcade-y and fast-paced this game is; However lowering the accuracy while moving would easily separate the players who are skilled from the ones who have no idea what they're doing.
This balancing method is used in other games and seems to be A popular way to make snipers good but give people (with good aim) a chance against them. Snipers will have to become stationary while ADS'ing making it easier for anyone to spray them down, especially in medium to close ranges.
Aside from balancing, there's plenty of ways to deal with someone who's scoping and I'll list them accordingly from my own experiences within the game.
1. Tactical grenades. You have them, use them.
If you know a sniper is going to come around the corner or where they're positioned, A well placed Flash/Shock grenade will make it near impossible for a scope to tell where you are and aim accordingly. I personally recommend flashes because it completely disrupts vision and incapacitates snipers for a short period of time but Shock grenades work too. Just keep in mind it's still possible to scope through them though, as it only blurs vision after the short flash.
2. Score-Streaks. We all have them, but some make Scoping hell.
There are plenty of options you could go for here from just knowing where they are (UAV, Spy drone, Stalker) to increasing your damage output or out right killing them (Escort Drone, Crawler). We'll start with the offensive drones first and then move onto the defensive ones.
Escort Drones are a real pain because a majority of the time even if a scope is able to kill you, they're still likely to die if you put enough bullets into them because your drone will finish them off. This also increases your time to kill under the assumption that your drone is targeting the same person you are, which could give you that extra bit you need to finish them off before they can fire their first bullet. I personally recommend this.
Crawler's are a bit more situational but still work just as a well. If a scope is holding an angle and you don't wanna risk peaking them, tossing a Crawler around the corner should do the job just fine. These things are incredibly difficult to snipe or even pistol as they're really small and you often wouldn't notice them being tossed if you're hard-scoping. They're also pretty good at clearing points and small rooms.
Now onto the more defensive, more support like streaks. The UAV, Spy drone, and Stalker all accomplish the same goal; Showing you where your enemy is so you can get the jump on them easily. The best thing you can do against a Scope is pre-fire them as you're coming around a corner, as they'll have to react quicker in order to kill you as you're already unloading bullets into them. It is incredibly important to memorize the map and how it's laid out as crosshair placement is crucial to succeeding; You aren't going to do much damage if you aren't hitting them in the chest or head.
Gorgon System is probably one of the most annoying score streaks for a scope to deal with as it blinds them making it difficult to impossible to spot enemies. A well placed Gorgon System can easily nullify any presence a Scope might've had especially if it's used to defend a point or to nullify a popular line of sight. Not very many people use it and I personally don't recommend it for anything except secure point; The spawns flip so often and unless your team is coordinated enough not to flip the spawns, this'll basically become useless when it's on the enemies side instead of yours.
Just a quick note on support streaks: I would only really recommend the Spy drone as your option for seeking out enemies. While UAVs cover the entire map and help your team immensely, they're also easily destroyed by anyone willing to shoot at them with a riffle or destroyed near instantly with if the enemy team has a LAWS up.
Lastly, USE YOUR SIGHTS! I CANNOT stress this enough because Hip Firing, while accurate in this game, is still incredibly unreliable. If you're not aiming down your sights and are instead spraying there's a much higher chance your bullets 1. Miss or 2. Do less damage by hitting the arms or legs. Every shot counts and you'll have a much easier time dealing with scopes this way, especially if they miss their first shot. If a scope can take more than 1 shot at you, then you are the problem and not the person scoping.
There are other things I haven't mentioned that should be common sense, such as engaging in your gun's respective range and waiting for a Scope to fire their first shot and then peak them while they're quick switching. There's also a couple tactics that I consider incredibly cheap that ruin the fun of the game that you could use against anyone such as going prone while spraying or bunny-hopping (Though in my opinion if you do this, you're just saying to everyone that you're incompetent).
Anyway, that's about all I can really say from my own personally experiences. Hopefully this helps for the final hours of the Closed Beta and hopefully in the near future if the game has an Open Beta. (Considering things don't change too much).
