Age of Strategy Forums

We were thinking of making a tech to unlock human units like hovercraft, hover tank, and hover rocket artillery (will be in next), that would make units like APC and mobile rocket artillery more useful and also would make hover less common. I think it doesn't have to be expensive (4 turns?) and researched in tank factory. Problem is that some of the human hover units are powerful early game... but maybe that's fine. I wouldn't want to give this to any other race, definitely not reptilians or avians, who can have more common hover.
