This job sounds like an overpowered lagfest. With 5 skeletons you're proactically a full party unto yourself. Healing 5% of your entire party's HP automatically every time they hit is insane. Your bloodlust would almost always be capped, since 5 pets = 25/100 points eevery couple of seconds. Add to the fact that your main character is getting +1 every auto attack, and +1 per tick from each of their DoTs... Honestly, there doesn't seem to be a reason for bloodlust at all at that point. Just make all of your heals free. /shrug Sure, it costs 50 for one of your special heals (Why does it cost bloodlust points to heal? Shouldn't that be for damage attacks?), but it's so easy to obtain, you'll be able to cast spells constantly with no penalties at higher levels.

Also, um... INT for healing and damage? So they've got this massive power, an army of basically immortal soldiers, and they gain the advantage of using their INT to cure and damage foes without having to change stances? It seems liek the ultimate solo job, but parties would be a mess. You wouldn't need any tanks or healers. You could get 4 Necromancers together and have 20% HP regen every 2 seconds.
