I think the most "genuine" approach would be to combine a higher priority group for servers 1 and 2 ; and a ratio set to 100 for server3 (but with a lower priority group).

If there was a way to just disable the priority group when a user is identified as premium ; then he would automatically go to the server with highest ratio (server3) whereas regular users would stick to servers with highest priority group (1 and 2)
