Amp stations should have a greater purpose than 'turret' overheat. Tech plants are pivotal in continental domination, especially on Esamir. Otherwise, the heavier tanks, MBTs have to be pulled from the warpgate. I think the Amp station should have an important, albeit lesser role in providing a meaningful bonus to those that take them. Turrets are highly situational whereas health regeneration is a tad more desirable (although I don't notice the effects with the Bio Lab at this point in time). One possibility I was thinking was a 5-10% increase to nanite generation rates, but this wouldn't stack with the amount of amp stations held on a continent. Another possibility is shield regeneration rates, bolstering the survivability of infantry slightly. Perhaps a 15% increase to regeneration speed. (once again, does not stack).
