Hasn't this always been the case? NA has always had a huge advantage but we just took it for granted for years that EU were so much better that it didn't really matter. Now that NA is competitive people are bitching about the time. I say just deal with it, WoW isn't an esport and never will be, you just have to deal with disadvantages like that.
Saying that, if all these guilds had to clear these raids at the same time in isolation then I can't see Limit getting first ever.
