Just HP stacking on enemies doesn't equate to an increase in difficulty

What? our Group melts mob packs in 30 secs with aoe in ShB dungeons..

At least on the first one, in my groups, this is true some of the time for some of the pack (roughly 28 seconds left on my dance consistently in certain sections). The pulls with some of the heavier adds take about a minute for the groups I was getting. Was a lot faster when we had some whm participating in the aoe (which is rare).
