I have to agree with ApolloIV, playing WoW with friends is the only thing that actually made the game really fun for me. You can have fun with a guild and all, but having RL friends is always a big advantage (IMHO). Personally I very much dislike the new content at 80, 60 and 70 content was good though. Its all a personal choice as im sure that many people actually do like the 80 content and for you it might be good since it favors more casual players as you are not as outranked by people that play hardcore (gear wise as least).
Just my .02
