That was my impression as well, at least in Big Top last night (the first Epic I've run since the update) It didn't really seem to take any longer to take down the held mobs without auto-crit than it did with it before the Update.
I would definitely like to hear what healer-types think of the Epic changes. I've hesitated taking my Cleric into any until I could get an idea of whether or not the resource requirements had increased, decreased, or basically stayed the same. From what I saw on my melee, the cleric didn't seem to use any more or less sp or scrolls than he would have previously (and I started paying attention right before Update 9 went live so I would be able to do a rough comparison)
