RMT Solution?

[Pandastirfry]

Get rid of shards. Its the easiest way for an RMT to make cash.

Then what? Get rid of crystals? After that clusters? Then low teir crafting mats? Though the "slippery slope" argument is a logical fallacy, in this case they'll always find something they can exploit to make their money.

The only real solution is to ban them when you can, they're kinda like cockroaches, sure you can call in the exterminator, but it's going to be awhile before you finally get them all...if you ever do.
