There is /fairfight list for solo/smallman (that nobody uses). In order to promote more use of the list and help solve the 1v1 / smallman problem I suggest the following:
Combine the GvG and Fairfight lists. If you are on the GvG list and add a small-man or solo that is on the /fairfight list, then you are auto-removed from the GvG list and can't come back for 30 minutes. You should not be on a list that promotes clean fights and have no penalty for adding all the solos and smallmans. Either play one style or the other. You can't be on a "clean fight" list and have no penalty if you roll over everyone.
