FYI older rotations were just used twice recently (two weeks ago and the week before that). I'm not sure how it was during the day when most of the EU players were on, but when I played later at night, I heard some complaints about a handful of the maps and some were skipped.
My main concern has always been to try and use maps that most players like (even if they're not ones I typically like) and to avoid the server killers. That said, I've certainly tried out a few in my rotations that weren't well received, but I've always been receptive to feedback, taken note of when players complain or want to skip them, and avoided using those maps in future rotations. And I've always said (as has Pengy): if anyone has any maps that they like and want to play, they can always make requests. Or do an entire rotation. It's not for everyone, but I find it fun!
