I'm in the same situation, and I'm suffering too.
With the previous system, there were less raids at the same time, but during more hours. And more important, you could see in advance when an interesting raid was going to start, so it was easier to find people just before the egg hatched.
I feel that way I could do some 4 or 5 level raids, but now it is more difficult to coincide with more players (less time to prepare, bigger window for each raid).
New system is better for people who play in groups, as they can do several raids one after another if they play during the right ours. But it is worse for people like me, I don´'t have a lot of free time, I just want to do 1-2 raids a day, the more interesting the better.
