I agree , in burning crusade you had to put the time in to clear the current content because the titles and some mounts would fall away when the new xpac arrived or was it before the 3.0 nerf, can't remember. However now we don't have to worry, i can go faceroll the madness title in 45 minutes at level 90 which a lot of players spents months and months wasting there lives getting.
IMO the game is much better for that now for the majority of players.
