I agree it's ridiculous to leave seats empty when you now have the opportunity to transfer them at the touch of a button.
The club does have a rationale for this particular decision, which I've detailed in the Ticket Exchange thread. But it doesn't meet their stated aim of encouraging and rewarding attendance. So they need to think how they operate the cup schemes while rewarding attendance & at the same time being more flexible about transferring tickets.
It can be done & I will be bringing it up.
