The TOR Railgun tank does not belong in breakthrough modes
The only reason anyone uses this tank in breakthrough is to camp behind their out of bounds area on one side or the other and snipe at enemy vehicles or aircraft.
Actually driving this tank into the objective is a one way ticket to to the respawn screen. On conquest its a bit more open and reasonable to use it, but in breakthrough there's no reason this tank should be deployable. Its just like the nightbird used to ruin breakthrough matches, the TOR does the same thing.
TOR camping has become a big problem in all game modes and I wish that DICE would make an update where deployable gadgets like the APS or Anti-Lock on gadget cant be deployed in any area that is considered a spawn area or out of bounds area. There's no reason to need to deploy these items other than to camp up with a tank and make sure no anti-vehicle weapons can approach it and no infantry can get to it because they will die before they get there.
Its not a fun gameplay style its frustrating and breakthrough especially would be better without the TOR Railgun tank being deployable.
