Who's big Idea was to remove Healing magic and Simplify Tactics

I too would like a few more AI settings. 

Here is my depiction of a mages usual AI behaviour. Understand that this is richly deserved criticism in the form of sarcasm due to increasing levels of frustration.

AI mage - Oh look a giant "Super Mallet" weilding heavily armored foe. I am going to go stand right next to him when he wildly swings his 100lb instrument of death. Oh dang, I am low on health for some strange reason - potion- ouch - potion - ouch- potion, no more potions?  I died, I just dont get it, I always die no matter how many times i attack in this fashion, hmmmm, lets try that one more time.

PS. After 124h in game I cant really say I hate it, I lost that priviledge after 10h I think.
