I could be wrong, but here is what i think:
The devs have neglected buffing the domina because they see the advent has op.
They see advent as op because (Red is what i see):
Vertigo: Chance hit 30%, cool down 30% (Rapture not really an opener and a victim to rushing)
Guardian: 33% damage spread (Vulnerable to ability disable without the domina but works fine)
Shield Mitigation Research +4% shield mitigation ( Requires all shield research to obtain)
Domina: Ability interupt e.g to stop emp ( Has to channel and face target, doesnt have to last as a disabler so usable)
Guidance : Ability cool down ( Opportunity cost high to getting another cap-usable )
Mass disorientation disables entire fleets including caps ( Starbase construction ship too expensive)
Is there a Culture Military bonus other than forcing opponents on using up military logistics for culture? How does this affect ships and how do u get it?
When all abilities are active (micro) = Ships receive little or no dammage at all.
If we concentrate on buffing all these key areas then its key to making the advent balanced:
The most notable consequence of them not having an econ is there suppose to recieve no dammage on paper but they need an econ to set themselve up:
Logistics is first and more econ bonuses via culture or other means. e.g an expensive trade port that produces 1.8cr/s
