Hubby on his new pally and I on my disc priest with two other guildies got into a H-HoR earlier. The random thing is wacky of course :P. Well it gave us an awesome enhancement shaman Dwellana who was very patient and when I died [causing our one wipe] she immediately started throwing some heals. In the most touchy parts she also threw a few chain heals to get us through.
So thank you Dwellana of Draka for giving us a very pleasant H-HoR run!
