give my two cents worth on the borg after i played using them this weekend
WAY....OP!!!!
the story:
So here i am with 3 colony ships and decided, hmm they have a the ability to assimilate, let see how badly colony ships would rock. Well luckily 3 systems over was a nice choke point, 4 nav point plus my 1. Mind you at this point i only had 2 fleet upgrades, and no other ships, Assimilation upgrades, regeneration and 2 weapon upgrades
after a few mins a pirate raid came for me, i assimilated 2 of the ships and destroyed the rest in the next system,
another few minutes pass and i realized i have now captured a few other frigates and some diplomatic ships
after 30 mins i was at -200+ fleet
after an hour i was at -400+ fleet, so i figured ok lets make this very interesting. I increased my fleet size enough to get a few spheres and just dumped them right in the same spot. After another hour i was sitting at -2000+ fleet and i walked away from the computer for about 30 minutes and i was at -3000+, looking at the fleets that were coming at me, i was destroying and assimilating a lot of ships. so i took my new borg fleet and steam rolled 1/3 of the map in just 20 minutes. About an hour after that i completed total dominaion.
now i never got past military 4, and civ 2. and i think i ended up with about -5000+ fleet points in the end. i could only imagine if i had built the unimatix station how much more that would own, and if i had nothing but sphere's that would own even more, Now granted every borg ship should assimilate, but the time between assimilation for each ship should be increased
