I personally like the individual upgrades.  Given the ramping up costs of things, upgrading new factories wasn't my biggest economical choke point.

I very much like the specializing stats system. The only downside is if you misclick anything, it's absolutely devastating. Factory health is useless, for example. And range turns into a downgrade when enemies can AOE your factories if your units are ranged and dont move away from the factories as a result.
