I see players not realizing the requirements to use episode clear tickets and looking for support extremely often.
While I think it's their fault for not reading the item description before buying, you can lower the frequency of accidents like this by adding a warning to the Temporal Tina NPC. After you click "Sure" there should be a warning text (preferably red) mentioning that some tickets require completing the quest on a different character first, that it will not work otherwise, that each requirement is explained in the item description of the ticket in question, etc.
