That said, consider what you just said: "you can go 12-15 months in retail with nothing to do". Classic will be an eternal content drought once the last patch is applied.
That's a rather meaningless to say, considering you can still do "BGs, alts, leveling, world PvP, roleplay, twinks etc" on retail, as well. That's like comparing the old beetle car to the new beetle, and say, in defense of the old car, "well, the old beetle can take me to the store, on the other side of town." Well, so can the new beetle car.
