I'd like to see more tech requirements for Stealth, between Radar and Stealth specifically. I think the hammer cost should be increased by about 40% and the upgrade cost from bombers needs to be at least tripled. But I'm also in agreement that the real trouble here is the power of RA's and GS bulbing. I'm sure the expansion will introduce a number of balance changes and I hope this is one of them. Self generated beakers should be made more important than it is now, that much I'm pretty clear on.
