So this is off-topic re the shattering, but I have a level 62 prot pally (now an awesome Tauren), which I had burned out on and stopped leveling pre-4.0. Just got tired of the rotation/general feel. Since I race-changed last night, I hopped on him to run a dungeon or too.
And holy shit, good fucking job blizz. Tanking on him is a blast now, really love the new mechanics. Definitely going to rush him up to 80. I love that there are so many buttons to push now, it feels really fast and dynamic in comparison.
Also, did they retune the Outland dungeons as well, or are healers just scaling less at low levels? I died once or twice on pulls that I should not have died on (I'm an experienced tank, not pulling insanely or anything, and I'm full heirlooms with dungeon blues). One of the healers was a resto druid who just didn't seem to know what he was doing, but even on the good runs I seemed to be taking more damage overall.
