Currency conversion rates adversely affect others

For example, if a player is in Malaysia, the currency conversion of Malaysian currency to U.S. dollars means that they currently pay 4x as much as a U.S. player does for the VIP pass, gems, etc. this should be addressed somehow because it will affect revenue for the developers and discourage players where the exchange rate is skewed against them. It should work in reverse, too, so that those with favorable exchange rates are paying the same price as a U.S. player.
