boycotting Pro7 is not too difficult, simply have enough F2P accounts active on US servers to give out to EU people who want to play there.
However this does not solve the language problem, many EU players don't have enough english language skills (my wife for example) this means I cannot give up my Valor toons if I want to play EQ2 with my Wife and cannot give up my Butcherblock toons if I want to play with my US friends, so I must pay double to continue. Which is utterly ridiculous.
It also does not change the bad experience I have personally had with Pro7 in relation to the account transfer from Bigpoint for Maestia, they lost my account, it no longer exists, and both sides blame the other.
