I've been thinking about this recently too. I would be happy to expand the number of available tracks in higher servers. It will mean that there will be tracks that a vocal minority will bitch about, but there are some tracks that I think people should be willing to give a chance. Let's look at the track list and get down to it.
Race 2 and Race 3 use the following tracks:
BL1_Standard
SO5_Standard
SO6_Standard
FE2_Standard
FE3_Standard
KY2_Standard
WE1_Standard
AS3_Standard
AS7_Standard
SO5R_Standard
SO6R_Standard
FE2R_Standard
FE3R_Standard
KY2R_Standard
WE1R_Standard
AS3R_Standard
AS7R_Standard
SO4_Standard
FE4_Standard
KY3_Standard
AS4_Standard
AS5_Standard
AS6_Standard
SO4R_Standard
FE4R_Standard
KY3R_Standard
AS4R_Standard
AS5R_Standard
AS6R_Standard
Pretty comprehensive list. There's not much missing from there.
