I'm aiming for that as well, but it sucks when just about every achievement I have left to go involves having to rely on other people to get them. It wouldn't be so bad if most of the people I knew didn't have this attitude of "who cares about achievements?".
I try to get people to run Malygos with me for his achievements and I get laughed at. It sucks.
Edit: Don't get me started with really obscure ones like [Lumberjacked (25 player)]
