I am strongly disagree with the policy of fiverr that any seller should have minimum 4.5 positive rating for sending Buyer request. It’s discourage New sellers even sometimes on experienced sellers.
You can not expect to get 5 rating out of 5 specially on any creative services like graphic or any design related service. So i think fiverr authority should take necessary steps to solve this issue.
I hope all fiverr community members will be agree with my opinion.
