Yeah i ended up using a mixture of profiles to get the job done mainly the questing ones from hordequest.google now im doing 70-80 with the allen profile its working ok just a few hiccups so far
If your class can heal, i'd heal and use Instancebuddy, awesome XP and on Call to Arms weekends i mixed mode which is also great XP. If your going to PvP use the Squire plugin so your not roaming around.
