how many players they loose everydays for being pure greedy bastards*[citation needed]* that dont care about their customers and only think about money!!![citation needed]
It's worth pointing out that the POP setup for the Centralized Server is far more expensive than setting up two server farms would have been, and was done for customer experience.
It's worth pointing out that in the past year Riot's given me two free Skins (a mystery skin and Captain Gangplank), as well as a free mystery champion (I got Jarvan), and they're planning on giving away a champion and a skin to anyone who places Gold or Higher this year (as they've done every year). This all in addition to the three free champions/skins that you can get as soon as you start playing the game (Garen, Trist, and Alistar).
It's worth pointing out that at the end of the day Riot is still a business, not a charity. They do need to make money.
