Warlocks using mage gear?

I recently listened to the WoW Insider podcast where the topic of the day was the Warlock Life Tap change on the PTR. While my guild's warlocks have been up in arms about it, I haven't paid much attention to it. Until one of the hosts on the podcast mentioned that warlocks might start to favor mage gear. That comment was worth a chuckle for a variety of reasons. Suffice to say, I doubt that any sane warlocks will pick mage gear, since mage gear isn't optimal for mages either. If warlocks (especially Affliction warlocks) want to waste item points on spirit and spell crit, go right ahead. Maybe some poor fool even spends dkp on a certain robe.
