seems like we engineers are getting a tough time what with our rubbish turrets that refuse to lock onto there targets and are easy to destroyed anyway. so lets give us engineers a chance when we are in the middle of a battle defending a room or somewhere by being able to buy an ability that will automatically only lock your mines or turrets to the white zones (you can only build on white zone but not red zones) so that you dont have to waste precious time shuffling about an area trying to get the mine or turret to turn from red to white. you would still get to place it on any white bit and in any direction you want but just wont let you move it onto red zones. this would make life a whole lot better when you quickly need to get that mine or turret built and i dont think it would make engineers a dominate force by having this ability.
