This whole tangent has intrigued me so I started doing more research into this class topic and among the articles I read I found this from yesterday which encouraged me.

There seems to be a lot of emphasis on melee healing so the Holy Paladin seems to have a cool future. Thats probably the direction I will go, 5 human paly's (for racials).

Now it's just down to PvP vs PvE.

Thanks all for your feedback and helping me see where the game is currently!
