It is certainly common to have a wide range of opinions about any changes that Google makes. We all have different expectations and comfort levels.
For those issues that you really find unappealing and don't think that you will be able to adjust to, please remember to use the "Send Feedback" tool (in addition to any discussion generated in the forum or Google+ posts.)
Google needs to hear about the specific things that people like and also needs to hear constructive criticism about those things that you don't care for. It seems to me that explanations about why you don't care for a particular implementation and how you think it could be improved are more likely to be considered for any modifications.
In the new design, the "Send Feedback" tool is accessible through the "Gear Icon" in the upper right area of the main part of your G+ pages. At the present time, it is missing from the "Profile" pages, but you can still activate it from a different page and describe what you want to provide feedback on.
In addition, you can review your previous feedback reports to see if you have forgotten to report something that is important to you.
