Aren't the majority of ah players peak time US flyers? Sorry you live across the pond, and there aren't enough of your people playing during your peak time. Why are we catering to the minority of players again?
Peak time is only a small time window and thus I wouldn't be so sure it's only a (small) minority of players playing during that time. And for sure it's not only those "across the pond", many US players playing during non peak times as well, for various reasons.
And only a fool would think making AH an attractive playground only during a 4h period each day beign a wise move for overall numbers, business and in the end not having a negative impact on peak hour as well.
As been said, trinity worked much better when we had about twice the numbers airborne at any given moment.
By the way, the numbers you are currently having at US peak hours had about been the numbers we had at euro prime time when I joined...
