I saw two reports in October, which are the most atrocious pieces of crap I've ever seen.
One was signed by an MAI and two SRA's which was full of errors and very questionable reasoning. No support of anything shown, but it was entertaining. That MAI was a huge fan of himself too as everything pointed towards his expertise and background. I guess that should be enough to prevent anybody from actually looking at the inaccuracies within.
The other was signed by a CG in another state about a property in Tennessee, full of USPAP violations and completely misleading. It was done as a personal appraisal, completed on the 1004 which is always a red flag. It literally had these exact words in the beginning of the report, and I quote:
"I extraordinarily assume that the use of this report is not from a perspective that would effect the appraisers consideration of value." 
His grammar was horrible throughout. He used comparables that were, well, incomparable to the property he was appraising.
In neither case, was I asked to review. In one instance, the report was sent to me in order to reveal comparables for consideration in another assignment. In the other instance, the report was sent to me to extract the deed exhibit, and the client didn't know how to send just the one page.
I say again - The whole Certified General versus Certified Residential versus Licensed versus Limited versus Trainee needs to be tossed, and competence should be the only controlling factor of who can appraise what after a license is obtained. Just as J Grant said, make the exam comprehensive and the qualifications strict enough to matter in order to obtain the license, and go from there.
