Thanks for your reply Boris, i've decided to run as a Paladin as it seems to be a good all round class and I already have the cross class skills such as Foresight and Bloodbath.

I've tinkered with Dark knight and leveled it to 51 and enjoyed the maneuverability of the class as well as the overall DPS.

Also regarding the Paladin class, what would be the best method for maintaining aggro during dungeons and raids etc..?
