Before WotLK I'd click on the target, cast a spell, then Shift+T or hit the attack button to get my felguard to attack. The challenge with this was that, especially when I was in a group, I'd sometimes forget to send my minion after the baddies and he'd sit around like a bump on a lump, doing nothing.
For solo play, with my felguard on defensive, this was great however, because I could tag a mob and draw him to me before my felguard attacked, reducing the likelihood of aggroing more than one mob at a time.
Since WotLK however, the moment I throw an offensive spell, my felguard races in to attack. Right now I'm juggling between defensive and passive buttons, so that he won't attack right away. However sometimes (as in pre-WotLK grouping with him on passive) I can't activate him fast enough.
So the question is, is it possible to turn off this new attack-on-cast mode so that he'll wait till an enemy is closer to attack?
