This reminds me of how at the beginning of 3e, people thought monks were broken. Looking at something on paper...First, I found it a lot better than I expected. Many things which looked broken or dubious in isolation turned out to work very well in actual play. ... Fears I had about fighting being a cakewalk for PCs were misplaced; unconsciousness was quite common and healing surges were burned through.

My paladin took a serious beating from the dragonshields in the first encounter. I was at 2 hp, then at 5, then 5 again, and had only 6 healing surges left. Those guys had more HP then anyone in the party!
