I think there should be a feature (or a spell) that allows myth users to take control of their minion, minions have become less reliable because they choose spells that are useless in the current situation of the battle.
if it were a spell: Spell: Visionary Pips: 0 (?) Accuracy: 100% Effect: Allows summoner to take control of minion's turns and abilities every round.
And maybe add new minion summoning spells and new minion buffs!
Here's an example: Unforgiving Effect: Places a +25% critical aura on minion. or Defender: Effect: Places a +40% critical block aura on minion.
