This isn’t a suggestion that would break the game or make minions better, but I think it might help MM builds to better manage their pets.
Suggestion: Life % display above the minion active skill icon.
Basically just what it says—just a number % ranging from 1-100 that tells the player what % their minions life is remaining. This bar would go under the buffs bar (pushing it up slightly) so that it doesn’t cover the CD time on icon itself (should someone be using that option). Since minions don’t regenerate health (save for the FG) I think it would play a small role in helping the player choose when to use those active abilities in the final moments of the minions life. This would be especially helpful with the Blood Fiend and choosing when to use his active heal.
I admit that really all one needs to do is pay attention to the HP bar above the minion itself, meaning that the suggestion is unnecessary. But I figure what could it hurt to throw it out there. I often miss the HP bars entirely because of their darkish color and it’s often hard to tell where the minions HP is in the heat of a fight. I suppose another, somewhat easier, suggestion would be to just make the HP bar itself lighter but I would personally prefer a number.
Anyway, just a thought.
