How i said before, i think nothing should be impossible in siege, even take a room with 2 or 3 sps inside, but mines are too cheap for this. We need to allow other build, or add a new build for this use as a bait in siege... currently if you have 2 sps in a nuke room, you dont need worry even a little with it, and the enemy team cant even think a way for get it, this is completly no fun, for attackers and defenders.
