Feat of strength is no longer awarded. The Lich King just says that you're empty inside like him when you kill all of the red dragons in Ruby Sanctum. I feel like a monster now.....o.o
So, back from the future and here's the result: oh yeah, it mattered. The Red Flight remembers your murders.
Like the mounts, just wish Blizz didn't chince out on the detail. The skin and bone effects look painted on by the developer of cheap Burning Crusade back pieces. If only they had given texture the same attention as the Frostbrood Vanquishers or... other class mounts...It's like finding last weeks lottery ticket with this weeks numbers and telling everyone "I'm still a winner man!". It's a creepy level of fail.
Sort of reflects what is happening in real life as we are driving all other species to extinction.
