@Maziodyne_@SkandiTV having had to go through it again on another character...it's actually pretty miserable until you get to the last 3rd of the 2nd zone.
@Brendzun I think a big part of it is that the fights are very scripted, so once a group gets a mechanic down it becomes very routine to repeat. Most of the difficulty is with progging.
@FeristalJ there's so many classes that having them all at 100 by no means indicates being competent with them. you just can't hold all of that in your head. Especially this late in the expansion when people have had things to 100 for 2 years and then never touched them.
