Quantumsuits are already in it's own expansion, Modular Powersuits
It's not the same thing to me, as the Quantum (especially with GT) is so expensive and so useful that it makes you a goal to reach in itself. Modular Powersuit isn't.
Upgrade modules are in Electric Expansion, but only for energy devices.
That's not the same thing at all --'. Upgrade modules in IC² are used to process faster, while increasing EU consumption ... Energy upgrade ? Just place one block more --'. (I know, this is the same things for machines, but while you can without problem use more space for Energy Storage, it's more annoying for machine).
I just don't understand. It is supposed to mean "kthxby" ?
