When the stated goal of the game is progression (and leveling is one hugely popular form of progression for most MMOs), any player who wishes to work against that progression should have to pay for that luxury.
The XP disabler price drop is great news, but I disagree that it should be outright free. Especially when TP is so easily farmed in game.
