This is a follow up post to my previous entry regarding AOE and your Alts.  I've been AOE grinding with my frost mage and my protection paladin, and all I have to say is that AOE grinding is better then ever.  The Frost Mage is a lot of fun with the fact that Blizard now crits.  With correct talent (here is the talent build I am using), and the glyph that allows for extra damage to the MOB before they break out of frost nova, that blizzard will crit quite a few times.  In fact looking at some videos from the past of a mage a bout my level (mid 40s) grinding with AOE and Blizzard I can say that my blizzard does double if not triple damage now, thus killing the MOBs on the second wave.

Paladins are even in a better situation.  It is easier to manage seals and judgements, and do additional DPS.  Plus the change to Blessing of Sanctuary to move it from DPS to mana regenaration is great, I no longer run out of mana while I'm AOE grindnign and can use more DPS abilities that relie on mana.  Here is my build for paladin.
