The AMP Station and Bio Lab currently have benefits that are a wee bit meh.
They need new ones, better ones and if they are to do the job intended for benefits they have to give your empire a boost when you have them and hurt when you don't.
A simple suggestion:
10% extra health for Bio Lab owership and 10% extra armour (vehicles) for Amp Station.
More Complex Suggestion:
No A2G missiles for Air unless you have Amp Station Benefit
No HA/HEAT for MBT unless you have Bio Station
(However, this assumes the warpgates are fully functioning, we have at least 1 extra continent and an inter-continental lattice. Each Empire would have a dsignated 'home' foothold if not sanctuary and HEAT/HE or A2G can be taken from the 'home' foothold at all times.)
You might think fighting against extra armour or health may be a little unbalance, however the benefit really has to hurt enough so that it influences strategic decisions and if 10% isn't enough to do that then perhaps increase it to 20%.
