Most of your problems boil down to Teen Titans and that's squarely on the shoulders of Scott Lobdell. Also, you got your wish (kind of) - they rebooted Teen Titans AGAIN two months ago from #1 again with a different team because of how badly it was mishandled.
I don't see very many other complaints with the actual New 52 in this post other than the valid criticisms of Teen Titans, which DC is certainly culpable for but I don't hold them ultimately responsible. I've been mostly fine with New 52, mostly because the Bat-verse was mostly untouched as you said (and like you said, the only downside is the compressed timeline not making sense.)
