Back in WoW arenas days people were buying Gladiator characters $1000-3000, depending of rank (r1) and gear (warglaives). While being a market with lots of scamming (people selling WoW accounts and getting them back with Customer Support) there is a lot of people out there not giving a single fuck about spending thousand of dollars / euros on online gaming, just because they can afford it / don't care about it. Even I was surprised when I sold one of my WoW Gladiator character, it's stunning to see people fronting verified Paypal cash over a single MSN chat with some random pics. You should see Camelot Unchained kickstarter, there are hundreds of people throwing $250 money on it just because "Mark Jacobs" and "DAoC".
I don't really mind people spending lots of cash in a game, it's like those people setting up their frontyard with overpriced garden gnomes. Only in Archeage they could buy more powerful doom robot sniper vigilante garden gnomes with machineguns, artillery and drones. You can pimp your stuff like a Christmas tree as long as it doesn't fuck with my garden gnomes, if you catch my drift.
