Warping in probes.
I think this could work because with proper scouting a player can either go units or workers or half and half etc. and the probes would/could cost 75 or 100 minerals ( idk if gas should be part of the cost) instead of 50 because 50 seems too easy to get ahead macro-wise.
Again, this is just an idea that could be fun for protoss. Any thoughts?
