I don't see a need to remove snipers from DT. I see a need for people complaining about snipers to get better with different weapons.
No shit if you're going up against a sniper in DT with SGs it's gonna be more difficult. Whose problem is that ? I'd say yours.
Get good with other weapons. Stop trying to take away what makes the part of the game fun for others just because you can't kill them with the only guns you're good with.
