Since the patch for scheduled city was released, is very hard play city sieges... The timer is bad for a lot of people, or when you can play, the city don't pop because the numbers of population are very unbalanced.
My personal example: I only played 2 citys since the patch be released (43 days ago!!!!). I queued 4 times, and only 2 gets pops, and when didn't pop, we was a 12 man, i never queued solo. And a lot of guild mates the same thing happened to them.
Here you can see the city log from Tercio de Estalia

We usually did 2-3 full WBs for city each week before the patch, and now we are only able to do 12. We missed 2 citys (in red in log) because we didn't get pop with 12 man (50% from my city queues...)
Please GMs, we want enjoy the game, try to fix it in some way. Some ideas:
-Decrease the timer from city to 3 days to 24 hours. So there are more chances to play for all.
-Lock the side to players. So the server population will not switch, 60-40% population when city pop is not funny.
-Get back to old campaign system
GMs, We are asking for your help, please don't ignore us, a lot of players want enjoy the end game content, but with the scheduled citys we can't. You are doing the game more easy for gear toons, but harder to play the endgame
