yeah until u hit HW u will be a bit "bored" while playing healer , u will get overgeared ppl 90% of the time in all the content...but once u hit HW u will not be able to stay on Cleric stance oustide initial pull (a bit more if tank is geared ) , u will find HW content way more challenging.

2.0 picks ups in the end , and its awesome , HW is cool too u will be :O :O :O all the way to 60
