When I play full minion, I don't get Conversion Aura 2 and 3. Instead I max Morals first and only get Conversion Aura 2 and 3 at 15+.
I usually get Amulet of teleportation or Ring of Divine Might. For Minion survivability I stack minion hp boosting gear plus Morale skill.
I put 1 point in Mist and/or Mass Charm if I need it to counter my opponents tactics. Otherwise I use those points to further enhance minions.
I max minion hp and dps so that it takes atleast 2 aoes to wipe out my minions and opposing demigods can not stand in my hoard of minions for very long. Mid to late game this will even work against ooze UB because it takes over 10 seconds for ooze to kill the minion hoard which is more than enough time for the minions to kill UB. Take way less time if you can batswarm in and bite.
The main disadvantage of my build is that it only really kicks in after level 10 and the full gear + idol requirements cost 22k so if you are getting dominated in the early game it won't work.
