The biggest problem with minions is they take way too long to kill (they are way too strong in terms of hp/dps for the # of them you get), and there's too many of them, almost every pantheon game is oak and ereb every... single... game. There needs to be anti minion on demigod skills I can think of lots of really easy fixes
Increase demigod damage vs minions and...
-Take away user movement from minions, so minions can't camp out and chase, It really ruins domination and fortress in pantheon. What is really insane is creepers and minions 2x ereb with creep death, the the amount of guys there is just way too much esp on small maps like prison
-Take away minions from ereb if he's gone creeps so he can't just keep spawning endless hords, ereb has good PVP skills, stun + teleport anyway. It makes 2v2 in pantheon unbalanced because minions just take way too long to die.
-Make minions always have to stay within range of caster.
-Make Torch Fire nova tosses all minions, or frost nova + bliz = instant shatter and and/or spells do 2x damage vs minions, this would do a lot to rebalance pantheon. Either that or limit the number of minions. Every game in pantheon = ereb + ereb or ereb + oak almost it's insane.
