Guilds in WOW

Ever wonder what the best thing in WOW is? I'd say it's your guild. Sadly the guild is also the worst part of WOW. Guild's are usualy formed with the intention to form raids to conquer content that a single player cannot achieve on their own. The problem is that the management of 25 people is difficult. Sadly mine just broke up and I want to level a horde to go gank all my former guild mates. It's just kinda depressing to watch all the hard work that I've put into something go down the toliet.
