Thank you for sharing your feedback.
I must say that I agree with you - there are some issues even with 5.1 SP2, but we had to implement the two new big features for 5.2. I am happy to let you know that we are planning to have 5.3 in December, which will be entirely focused on bug fixing and PITS issues, with no new big features. We are also planning to have 5.2 SP1 with again polishing, rather than new stuff. So to recap, in the next 3 months we are only going to push service releases.
We apologize for the negative experience, but I am happy to see that we are aligning with your expectations.
