I have pretty good raiding experience. I raided on Darrowmere with Afterlife during BC and some WOTLK. They were the best guild on the server. In BC I participated in the death of: Illidan, Vashj, Kael'thas, Archimonde, and more. After that I became more casual so just did some Ulduar, Naxx, OS, and Rs.
What would be awesome is a guild who is just looking to have fun. Not enough for 25 raids? Try 10 man or form a bunch of heroic groups. I dont want the guild to make me feel like the game is a job. Feel free to ask me any questions or PM in game thanks!
