I don't know how casual you are or how long it's been since you last played, but Blizzard flipped everything around for casual players not in a guild with Cataclysm. Those features you name are still there, but now they're next to rated BGs, guild achievements, and more features you can only really get while playing with a group of other players, i.e. a guild. Even basic non-raiding perks like 15 minute hearth and increased xp/rep gains are tied to guilds now. I had an alt that wasn't in a guild or cared to raid that just recently joined the <reddit> guild because I really wanted those perks while being in a guild that didn't demand anything of me. I only raid a very strict max 3 hours 3 weekdays a week on my main toon in another guild and I refuse to tie myself down with raiding on a second one, and <reddit> is perfect for that...people are always online to play with, raids are always going on if I ever want to check them out, but I'm free to stay in the guild with zero commitment towards any time sink and I can solo all the content I want. You might want to check out joining a similarly large and open social guild for yours.
