Why Speed Pulls?

[DenebPunkin]

I appreciate your response, but it is not an answer to the question I posed - and I have a feeling you're sidestepping the question.
A completely unskilled group will fall flat on its face from the get-go.
What I asked is:

Both require the same skill. Bigger pulls means the tanks have to pop more CDs, and healers actually have to throw more heals instead of throwing a heal... waiting a few mins and throwing them again. The difference is you have to be a little more alert.
