Problem:
Because minions are monsters, they inherit some stats from monsters that can significantly affect build choices and power. As these stats are not detailed anywhere in-game, they are a cause of confusion for a lot of players (as well as rendering minion ailment builds near-impossible except for minions specifically designed around them). The large damage bonuses granted to minions by frenzy and power charges also crowd out alternative options, especially for shield itemisation with Necromantic Aegis and utility-focused spectres.
Solution:
Split potentially-confusing monster stats into minion and non-minion versions so that minions can behave in the manner players would naturally expect.
