It was never about accomplishments with them. It was about finding ways to sneak in backhanded insults at every possible opportunity and inflating egos by misrepresenting things until they can convince themselves they mean something.
They covered the fact that they gave up on the US servers by saying that the lag on the US servers is minimal, but that the "real reason" they left was that they couldn't find any players who were good enough on the US servers.
Doesn't that seem the slightest bit dishonest and maybe a bit underhanded?
We've all felt the lag on the US servers. It's not like having them repeat that it's insignificant for 10 pages will eventually convince us that we've been mistaken. So why bother doing that? Because it's great troll bait, the same as all of their other obvious misrepresentations.
