Thats around 3-5 am central european time, if anyone was wondering.
Would be much more likely to find opponents in euro late evenings. 5-6 pm your time. There are however some US based coalitions, they're just not active much. Best bet is to check coalition index when u are 3 people ready for a cw, see whos got 3 or more online from otehr coalitions and just private message them
