When buying +Minion Health Items (Hauberk of Life, etc.) and using any General but Erebus, your minions have their original health when summoned and not the boosted health.

Erebus has this problem only without skilling Improved Conversion Aura. After he skills this he has full boosted health minions when summoned. Other skills like Entourage or higher Raise Dead Ward or higher Summoning Yetis or Shamblers do not help!

Quite a disadvantage for the other Generals and hardly intended, hm?

Edit: It's even worse.
