I'm firmly on the "cannot be gotten in-game" side of that divide; I do respect what DoD are doing to the contrary as a last-roll-of-the-dice gamble, but I wouldn't approve of it in a new game and I wouldn't actually spend money on DoD's offerings.

It's just too murky an area for me - charging real money to the studio to bypass the in-game costs or efforts... that the studio set and maintains?
For instance, personally I don't consider Cryptic have an ethical leg to stand on charging sizeable sums of real money for respecs to bypass the exorbitant sums of virtual money that they're charging and could alleviate with a few keystrokes.

I know all MMOs exist to prosper and make money, but part of MMO fandom should be able to empathize with your chosen game's devs to take on the big ol' world: it's easy to feel comradeship with legacy game teams and innovators like Anet and the Free Realms team, but kinda hard to get behind developers when they're putting hurdles & toll booths in your path 30 days from release.
