Locking the number of exos

You need to add a feature that will allow the commander to lock the number of available exos. Simple and efficient.

I won't upgrades exos anymore it's fucking dumb how often they will cost you the game because too many marines will jump into one as soon as they are available. And yes even if you take great care at warning them.

I'm done getting frustrated to lose a long and hard fought match and seeing peoples get angry at each others because one unit become available. It shouldn't be that way.
