100% agree with this.
I have cases with repeat clients who left 4 star reviews and later messaged me on Fiverr that the new rating system is not clear and upon review it appeared to be 4 stars where they intend to leave 5 stars. These are not new buyers they are experienced buyers regularly ordering on Fiverr. If the new system is hard for them to understand then you can imagine who bad experience it could be for new buyers.
Replacing stars with emojis on a professional platform makes no sense. Emojis are replaced with the stars later when the review appears on the seller profile, most of the buyers only then know what actual rating they gave.
"Very good" should be the highest rating level instead of "exceptional".
Buyers don't place orders to fill these complex review forms etc, they are here to get their desired services. The review form should be simple and easy to fill. It should not be something scary and lengthy that buyers face a hard time filling. On top of they are annoyed with a private feedback which does not make any sense. This is too much work for a buyer to do dedicatedly without any benefit for them. That is why most of the buyers don't bother to fill them.
