Thirdperson should be removed or changed or fixed or something. Its extremely unfair when you have people that will abuse it and bind it to a button that they can change at will to give themselves an advantage when in a fight. And yes, this is on the minigames server and there is not a lot of instances where it is useful against the other team but it still is unfair. Whether you're on Swag Multigames doing the 1v1 deagle or Smee Tower, or any other map that involves guns and shooting the other team, using it to see around a corner or above a wall when you normally should not be able to unless you show yourself by jumping or moving is abusing the command.
I'm not sure if this is something that's already enforced or looked upon or if its included in the abusing Exploit/Command rule but it should not be allowed. Playing on the minigames server today there were a few people abusing this to their advantage. You can look at it as wallhacks in a way. It makes certain scenarios unfair especially with the whole betting system.
Now I understand that this is not a game breaking exploit its just something that's not fair, but I still think something should be done with it.
