That makes no sense!! I can understand the fa cup and league cup as there's no pre-req however, you can't have one set of rules for STHs and another rule for members...that needs to be reviewed!!
Same every year mate:
1. ST get the opportunity to reserve their seats for all cups with the Autocup system on ST renewal.
2. ST choose Autocup seats anywhere available in the stadium for each competition if not doing method '1'.
3. Autocup window opens for all, but possibly with pre-requisites.
4. All remaining tickets sold on a match by match basis, almost certain with pre-requisites initially, down to general sale if applicable.
