its fun, you can always pick it up whenever, i quit since burning crusade , missed 3 expansions, and just recently a month ago started playing WoD. i was able to get a char and lvl him up to 100 and get most of the season 3 pvp gear with ease and remembering where i picked off... i mean its pretty basic and if you lvl from the beginning you will defenitely learn you chars and pick up on things quick. it takes skill to be great at this game, but practice makes perfect as if with anything else..
