I'm finding it to be fun, in a challenging way.  Of course, most of WoW's mechanics don't factor into RL.  For instance, drinking water to restore mana is a game mechanic to lessen downtime.  I'm fairly sure that in the lore that mages simply drew power from other sources in large quantities, then used it until they were low on power, and drew again.  Sleeping and other more mundane ways of resfreshing yourself also help.<br/><br/>But, I stray off topic.  :P  My point is that taking game mechanics and figuring out how that would work in a more realistic setting is fascinating to me.
