Pffff, any NA honestly think HCE would have merced for them if situations were reversed?
And people can see your nighttimes before they attack you, if your night time is set so that they can only attack you at a shit time for them or a shit time for you, the choice is obvious, any NA strategus player would make the same choice if presented with those options. Or you just expect them to go 'hmmm, night time over the only time our peak hours overlap? Guess i'll just ignore this fief then'?
In NA, We'd attack at 9PM or later so every NA player can join the fun. EU's can't hang with that time, then they need to fuck off.
Oh, and a FYI, Dutchy basically did/does this. So, no one attacks him during weekdays, but he modifies it for Weekends(sometimes he forgets), so that everyone can get good battles(himself included). We can do agreements on things like this during weekends, but apparently, EU cunts don't have a balls for this. It's "their way or the highway."
