Yes now in game ~60% Brazilians - and for game its catastrophe... NC.West make big mistake when start orientate game in South America... Need understand that in S.A. - approx. all countries poor - and they not pay for game. People forgot that some years ago was Brazilian server - which disappear (because people not pay).
America (USA, Canada) - can compare with Europe, if we talking about West Europe - its aprox no diference. But if we talking about South/East Europe - impossible to compare - they are poor (and even have money - not want to pay). This people credo "im scammer").
And all this regions impossible to compare with S.Korea. Korea small rich country - and most gamers pay for game.
About prices its simple... Lets say (its just example) Korea server have 2000 gamers - for game pay 1000-1500 gamers (so server can get profit even for low items prices).
Nc.West also have 2000 gamers - but pay for game max 100 gamers (for server also need profit). So NC.West orentate in this 100 gamers - and from this people (supports) getting money. To make price less - its not solve any problem, because this people who not pay now - not will pay newer. I cant imagine that Russians, Moldovians, Romanians, Grecians, Polands, Ukrainians, Lithuanians, Latvians, Brazilians (its base of NC.West gamers) and etc start pay for game... This never not will happen. If here in forum cry about "prestige" price... what can more say... they not have or not want pay even simple 15$....
