Hello, my two cents on Nova Co-op.
Even with the changes, the units cost so much there is no real benefits to changing her soldier of fortune prestige. Even if you were able to get the cooldown faster, you wouldnt even be able to mine resources (gas mostly) fast enough to keep up with the CD, especially if you go air. You might be able to pull this off with Bio, but not much else.
Her prestiges are really not worth investing in as each one hinders her more that benefiting her as a whole. truthfully her prestiges suck as of now. No one is tactical jumping continuously, and even with supercloak, she still needs units to support her (the units end up doing more damage in the long run, lets be real even with the attack speed increased, she shoots 2 shots a sec, and thats really, really giving her the benefit of doubt.) which makes this perk useless. Ive already mentioned the mining.
