I'm in what you probably would consider a top 1% guild, rank 80 Gul'dan and there's a big difference between us and top 5-10 guilds. Notdev already covered most of the reasons so I won't really bother explaining it to you again. And I don't care about your probably end of the expansion cutting edge, the fact that you said you didn't even know anything about this topic until very recently means you clearly aren't the best for arguing about it.
