Not sure what races that you have been in Troels, but I have enjoyed the Seat series and now the Arbarth series. I am certainly a beginner as I am a few seconds behind the top times recorded on SRS. I have seen up to 4 servers being run on some days - with 24 cars per server.
But, I do wish that they could group all the top qualifiers into tiers. You get rating points for races joined and if you have raced in SRS a while you quickly accumulate rating points. While I have a high rating due to joining in many of the races, I am really not good enough to race in server 1 races. There are always drivers in the server 2, 3 etc who have much better quali times and should be sorted into the higher server tiers.
However, I enjoy the racing as it is free and "built into" AC. Unfortunately most of my incident points (as I mostly start near the back of the pack) are derived from mid pack T1 mayhem/lunacy. It is from this position that I normally gain several places if I am lucky enough to get through the carnage unscathed.
