plz not, for sneaking it is sometimes very important to place proxys in enemy buildings
it is a horrible idea, because it makes defending for example on field very hard with mines. if a feature would added like that, I would stop to try defending via mining in tuns...
the reason why I ask for more mines was, on field I tried to defend the bar in tuns, but I felt like I was just the whole time running to get 3 mines
and is not really fun to run the whole time between tuns and PT, I wanted to do other things too
