Honestly this suggestion itself is not as bad but leaving a rating towards a server in the community it could be said in many ways, there is no need for a special section where people could only rate a specific server there.
Another reason why i am against this suggestion is because many servers have the option to Vote which that itself makes it a positive review. Where if u wouldn't vote a server is not necessarily a bad review but it gives you the idea that people are not interested in.
Plus it could create many conflicts between servers which are super unnecessary and I will hope these conflicts will never happen.
