From The Escapist:
Hm, that sounds pretty good actually. I let my sub expire because all I had time for towards the end was a few BGs per day, and it wasn't worth the money.Still, being able to play up to level 20 on as many characters as you want is a pretty good deal, especially since the newbie zones are arguably some of the game's best content following the Cataclysm expansion pack. Hell, you could stop at level 19, twink yourself out, and engage in low-level PvP for free as long as you wanted.
How's twinking since Cata?
