They pretty much clarified everything when they released the patch. They stated that this patch would essentially change every aspect of the game, and that after 1.19 they would have to fine tune things. Some of that tuning will come in 1.19a, the rest over the course of 1.20, 1.21 etc.

As far as a lack of developer response.. Well, they just did the live producers letter, as well as translated it for the various regions. Also, it doesn't take a rocket scientist to look at the extensive patch notes for 1.19 and come to the conclusion that, perhaps some of the developers have taken a couple vacation days to decompress before putting their nose to the grinder for 1.19a and beyond.

In short, you are over reacting. Instead of getting all worked up about what you perceive as wrong in a patch that touches every aspect of the game, and isn't even out a week yet, how about you take some time to enjoy the work that was put into this patch.
