Subtle hint in his post is that we will forever be second rate customers in this game. Besides what he mentioned germans have better bonuses on gem sales better compenstation for mistakes more competitions celebrations of important days etc.
If I was fluent in german id have changed to german server a long time ago.
Dont be too sad though there is a third rate customer bracket. The unofficial test server of the live servers - currently french server. There everything can be messed up in live game and noone blinks an eye. Like last halloween the event resources were converted to coins before the event ended. BB didnt restore what was lost they just used some formula and sent a pile of pumpkins to people. Some got more some got less. Nothing to do but deal with it.
