So using it is abusing it? Okaaaaayyyy

Just need to make other weapons more competitive just wait till they bring heavy machine guns back in the next update sleeper wont be used as much

Here the thing. Everyone has an opportunity to have a sleeper. Everyone has the opportunity to use it in that game mode. It's not unfair at all. Either counter it or be humble and sit down.

You missed the part about rampant abuse. I’m not worried about it for that reason, I’m aware I can use it. Anybody can use it and be successful. To the point it erases skilled play. Which is the problem. It removes an element of skill. It also becomes the only option. Do you really want gambit to be a laser tag arena? Doesn’t mean it’s not still a problem just because anyone can use it. It’s better than everything and there are very few counters. So it’s out of balance. (Also my Queenbreaker beats Sleeper nearly every time, so hush.)

How is the queen breaker any different? They both require aiming. It’s not like you can just shoot anywhere with the sleeper and get an auto kill. I’ve killed invaders who were using it with my Ghost Primus. Maybe you should just not be such an open target?
