Hey between my brother and I we have a lvl 70 discipline priest, a lvl 45 frost mage, a lvl 40 fury warrior, a lvl 28 enhancment shaman, a lvl 23 feral druid, a lvl 19 subtlety rogue, a lvl 15 affliction warlock, and a lvl 14 marksman hunter.

Which is the best class?

Well the priest is mostly his (I get on him to make money), the mage is mine (absolutely love him), the warrior is his (he's fun as hell), the shaman is mine (amazing), the druid is both of ours (pretty fun), the rogue is mine (fun but getting boring), warlock is mine (hard to keep playing him), the hunter is mine (fun as hell, so easy to lvl). 

So which is the best class?? Well for starters I would say use a warrior or hunter.  They are easy to understand and fun to play.  For people who have a lot of toons I would say mage, shaman, or rogue.  Decent to learn and very fun at higher levels.  For very experienced players who have at least one lvl 70 I would say warlock.  You understand how the game is played and like being the (bad ass) lol. 

I'm not sure what the object of the post is actually lol...but any thoughts or comments are welcome!!

I have a shadow priest and a frost mage.  I like them both but just dont know which one to stay with.  I like that as a mage people can rarely touch you, but if they do your dead.  Priests arent as strong but its a lot harder to kill them.  Which one would you personally recomend since you have both a priest and a mage?

if u want to raid and do instances, keep the priest, id choose the mage though
