You were 100% correct. This happened to me just now.
The buyer was left satisfied with a 'great experience' and said 'great communication' but still left a 4 star review. After completing over 2,500 order on this platform, I am sure that at least the 'Seller Communication Level' would be 5 stars instead of 4 stars in this case. (Great is not very good).
Hence, I agree that the buyer has 'punished' me without him knowing about it just because the 'exceptional' threshold is just too high.
Someone said above that it would be more consistent to be:
Very poor -> poor -> average -> good -> very good (or this could just be great and not exceptional).
With 'Exceptional' being a rare occasion and the buyer can, thus, tip.
Fiverr is just trying to differentiate sellers even more. If more sellers have ratings of 4.7, 4.8 etc, then the 5 star rating will have more value. Nevertheless, this will drive sellers into the ground with much more demand, effort and work. You cannot simply deliver 'Exceptional' work in every single order. Sometimes you just do the work according to the requirements, why do we have to give more and go 'above and beyond' every single time?
This raises the expectations of clients that *every single time* they will get more than they ask for. This is a massive risk for sellers. If clients have such unrealistic expectations then it will definitely drive sellers into the ground with a lot more work.
