Ongoing - Estimations of class function and power?

[Nystul]

I had been teamed up with a Warlock, and found that his minion would act "stupid" sometimes. Like instead of it going off and attacking one monster that was alone, it went for a group of 3 monsters.

It is possible for a warlock to micromanage his demon as closely as micromanaging a unit in any other Warcraft game. Of course, some people are better at micromanagement than others...
