Sorry but based purely on what has been posted above I feel you have no right to complain about those evening peak changes (unless I'm missing something) one train has been made 10 minutes later, with a couple of other basically negligible changes. And while everyones pattern is different, I'd argue that represents a small improvement, for anyone that finishes work at 5 getting to the station for 5:10 could be a bit tight, esspecily if where they work is not right by the station. The lose of a through service from Deansgate is worse, but it isn't possible for the many other changes happening across the network to happen while keeping ever other service identical. Trams between Deansgate and Oxford road are very frequent. And people near Oxford road could walk to Piccadilly considering the slightly later departure. Overall I'd say an improvement for people at Piccadilly but a worse service for workers at Oxford road and Deansgate, no I have no idea where the distribution of workers is for people getting on at CNG. But I'd still say the changes are minimal and alot less worse then your making them out to be.
The service being moved 20 minutes earlier in the morning will mean and early departure and get up for many people, which will understandably annoy them, but again, if your criteria for adding improvements to the rail network is never changing any of the current services then you aren't going to get very far.
