I distinctly remember 2 FAs ago that the only reason I knew about it 72 before the start is because someone who's on the US forum too wrote here that the mods there announced it. And this time even anonglitch announced it on the forum before the in-game announcement appeared.They did get a really long delayed roll out of the new relic/KP distribution of the latest tourney changes (like months), but it is not true that they get any advanced warning from mods about FAs. Helya has said she cannot announce FAs until they go out on the in-game horn announcement. Most of it is speculation and word of mouth from what is happening in Beta, but not from any official channels. I feel like it's the opposite experience. We get new features in the EN market before US market so I know more of what's going on from playing on EN servers. When they consolidated tourney format to only 1 encounter instead of 4 per province, we also got those changes way before US servers. Those changes drastically made 10th chest easier to obtain for most fellowships so more blueprints for longer here.
p.s. US servers ARE getting mandatory moves too. Options in settings to opt out have been removed as well.
As for the tournaments and other features we get before others because they want extended testing, I guess that's a matter of opinion. You liked those changes so you think that we are the ones in a better position, I, on the other hand, didn't like them, they made tournaments more difficult for me, and put a halt to my game progression, so I see us as unfortunate guinea pigs
