Chronoscrolls will not deter RMT. By definition, Chronoscrolls ARE RMT. It is just that wealthier players become the RMT for poor players who don't mind paying more money on top of their monthly subscription for an in-game boost.

EVE has PLEX, and if you go to any RMT site you'll see the RMT using PLEX as a currency for their activities.

Will it help lazy people from getting hacked? Probably. But that's not the point - the point is the effect is has on the game economy when anyone can pay $XX USD for a large amount of gil regardless of ability, level, persistence, or knowledge.

I'd rather have a game world where people need to think long and hard and twice before they decide to open their real world wallets to buy in-game gold. Just because restricting RMT is hard and complex doesn't mean its not worth doing completely.
