For anyone who played, would having the spawns be the sewers work?
I'd block off the entrance into the sewer at mid, make the stairway in the sewers lead to a spawn exit, which would be taking a right to the intel or taking a left to get to mid. Then, you won't be passing by the immediate spawn when taking either route into the enemy's base, and since both exits are far from eachother, if one is camped, the other can be used.
