Q:

Is there an easy way to distinguish party summons from enemies?

As it stands, I'm already clicking my damn arm off, and more recently I've played with several Witch Doctors who summon minions that look like enemies.  In a large melee, I often end up attempting to target them before, during, and after the main battle - until I find myself clicking away at a friendly while everything else is dead.  Is there some visual clue that can help me focus my Barbarian's man-wrath on the (enemy) hellspawn only?

A:

By default, pressing 'V' on your keyboard enables enemy health bars.
I find that easier to identify enemies and you can usually tell if you're overwhelmed as well.
