I play this game for more than 10 year and never before have we been in such kind of situation where attack protection was activated during Christmas... Why did it happen this year?? There is no reasonable excuse for that move.
If you wanted to give people time to spend it with their families then you should do a poll with a proper question.
Why??
We have escape flights and vacation mode. If players would like to have a stressless Christmass then there are already tools to do that !!! It is their choice to play or rest during that time. You made this game dead for 3 days and you hurt players who prepared for Christmass by going into vacation mode. They might feel tricked. They lost their resources because there were no info about your attack protection plan.
Next time you should consult that kind of moves with players or inform them earlier. It is not only my opinion but many other top players feels the same way.
If there was a poll then majority wins and there is no discussion. Not the way you did it few days ago.
Best Regards
