A couple of other things I'd like to add.
Some of the (possible) changes I have been banging on about would help smaller outfits, e.g. engineering deployables and minefields which with other changes make outposts and bases more defensible.
And it's true, at present once the zerg gets moving you are nothing but a small bump in the road.
The second thing is that Higby has said in the past that he want to make or maintain space for spec ops type activities to still have a role. Now, given that spec ops isn't suitable for the larger 100+ outfits then I'd assume that Higby is open to good suggestions on improvements that might be made.
