Someone can use alt accounts to act as cameras, making sneaking around useless. There is no way to defend yourself from this.
-If someone is hiding behind cover during a sniper battle, for instance, one can have their alt move behind them so they can know where their opponent is going to pop up next.
-Another is the problem of having "eyes behind your back". A player can easily camp, using both screens to see all around them.
-If a player is exceptionally resourceful, multiple alts can be planted all around the map, Making it very easy to harass players that do not want to fight them.
-If a player or two is setting up a trap, one can send out their alt first to give away their positions, making the trap pointless.
A strong -1.
