Dude, thing is, no matter how late you come into WoW, as soon as you hit the level cap, you can go back and solo all the old content if you want to get the story, or you can wowhead, people aren't as concerned with what you did prior as long as you are good for what is current. I took a year break and returned about a month ago, and just got right back into it and am having a blast again, mainly because I played this and went back to a game with content. Now I am super excited for November 13th.
