Putting is clearly different after the patch. Speed seems to matter a lot more, which I won't have a problem with so long as the new behavior is consistent. Before the patch, I think it was a little too generous with how hard you could hit the hole without the ball skipping over it.
However, I understand the OP's complaint. I can see how people who put a great deal of time into mastering how putting worked before would be annoyed by these unexpected changes, which are not insignificant. It has been annoying for me to miss puts I was making before, but I'll adjust.
I think this game has been out too long for a fundamental mechanic like putting to be changed now. Putting was unrealistic before, but it was good enough, and people had adapted accordingly. There are still unfixed bugs after the latest patch, and there are so many things other than putting that could have been prioritized. For example, I don't understand why they took the time now to mess with putting when people still can't complete certain challenges because they are broken.
