Umm, there was no real racist comment made.
Anyways, I think that they should do the whole IP block for countries, but I don't think it would be a good idea to make it U.S only. Personally I think it would be best if they made it U.S/Euro only. I thought this WT was supposed to be for US/Euro only, but instead people coming from all over the world are playing it.
Like previously stated by harmnone89, most of the dedicated players came here for reduced lag. I think most, including me, came here hoping that, if aeria games didn't get dedicated servers, it would at least keep the players not from euro/us off their servers.
At the moment, while this is supposed to be US/Euro Wolfteam, this is still the same international WT with a few mods.
BTW, I think this should be in the suggestions section.
