I have noticed that Lugan the Steadfast's A1 is not healing the proper amount whenever he attacks one of the Ice Golem's mionions.  He should heal for 25% of the damage he inflicts.  This works against the boss himself, no problems there.  However the minions are a different story.  If my Lugan strikes a minion for 60 000 damage, he should heal my team for 15 000 HP each.  However, he will only heal them for 3000 - 4000 HP.
