When not raiding on my beloved resto Druid, I am leveling a Pally alt. I generally get bogged down with alts around the mid-40's, but my Pally just hit 50 and things only got better (Crusader Strike ftw). I don't feel like spending the 1k gold for dual spec just yet so I was curious when and if I should switch to Prot for leveling. Outlands perhaps? Assuming folks think I should switch to Prot, any suggested builds?
Edit: The reason I would prefer Prot is that I'd like to tank instances as I level.
