It should be more than possible. Also take into account that the first ten or fifteen levels are all pretty much on your own anyway. Still, for the really social players, there are always some new players or lots of alts out there too, even at that level.
And you get the entire game, all expansions and adventure packs, for the price of only the latest expansion, Rise of Kunark. So if you get that one, you'll have access to it all, very handy and cheap.
