It's a game, plain and simple. I think sometimes serious raiders tend to forget that, forget to enjoy the game. We wiped non-stop on Arthas last Wednesday, but I had more fun than I've had raiding in a while. One liners left and right coming from the guildies, including a couple that made it to our Guild Message (sadly not all could fit!). The repair bills didn't matter, we were having fun. What a novel idea. Having fun while playing a game ;)
Here are some spells that we've re-named in the process of having fun with ICC.
Love Chain: Pact of the Darkfallen
Fire Farts: Swarming Shadows
CHOMP!: Frenzied Bloodthirst
The Clap: Necrotic Plague
I'll have to post some raid quotes another time, but they're usually quite hysterical XD
