Saw an interesting conversation in EC about Druids.

Ok Question for you all. Friends play a bard and a warrior, we are levelling together.
Is my druid going to be fine healing them at higher levels (14 at the moment) Or is it actually going to go a lot slower?

I'm seeing the bard as being on slow duty.
I can't see a huge mana efficiency difference between Clerics and Druids, unless you are just going to rock out 1 CH a battle and ride on that?

Looking over the spell lists it doesnt look like things will start to change until 40s (shaman have canni and clerics have CH).
Thoughts? I'm not HUGE on what class I play really. thought druid would be good with bard, giving us the ability to kite, but I don't want us to be feeble in tanking situations at higher end.
