Well I really don't mind drinking to be honest. My main has enough gold to buy me unlimited water until 60, and while I drink I usually alt- tab and surf the web. That plus I don't buy gear at all on the AH unless it's a really good deal (got a 1h blue mac for 10g). So I just wear what I get from drops and quests.

And unless the mob is orange - red, or an elite, I can usually lightning bolt him down before he does any real damage. Plus if one of my guys gets hit and the casting goes back some, the other will still get it on normal time, so aggro switches between the 2 a lot.
