It's far too generous on points, but I guess you know that already. I'm getting 3 times the points for a win/fastest lap for what I would get on Race2.
I suppose the Race2&3 + UFBR -servers should all give the same so it's not a matter of which server/car I choose to race with if I want to hold on to my spot in the rankings.
That is if the UFBR server isn't going to be a entry level server.
