No I mean as a purchasing agent like Kobans. Obviously not at the same level as a Koban (Gold piece) when you consider monetary value for the site (and the site needs that to generate revenue), but if you're really ancient like me and remember Green Stamps then something like that. Back in that day you would get so many stamps based on dollar amount purchased at participating stores. You saved them and they in turn could be redeemed then in the hundreds or thousands for 'gifts'.
For a simple example, set a 10 to 1 ratio of Champion tickets to Koban value. A legendary Ginseng Root in the Market is 90 Kobans so using this example you could redeem 900 Champion tickets for one. Devs would obviously have to set the ratios and it would require additional coding in the game for another means of barter so this may be a pipe dream. But it would provide a use for the tickets whose purpose has been lost. I have all 6 Ladies from the Champions in my Harem and the other gifts for a long time now and it's pretty superfluous to expend the time and effort to go through 5 levels just to receive a single orb or some Kisses for the Seasons play.
There's a thought there...if the Devs could figure out a reasonable amount of tickets required make them redeemable for your choice of an Orb or 10 Kisses for Season play at the Reception desk. Kind of the opposite of where you can purchase tickets for 60 Energy points or 120 Kobans. Add a 'Redeem Tickets' button(s) there for the Orb and / or Kisses for 250 or 500 tickets or whatever value is a fair ratio. Usually it takes me about 20 tickets or so for a good draw of my girls against the Champion to complete a level. That would be 100 tickets for all five levels. So 250 or 300 seems to me to be a fair amount of tickets to redeem as this is kind of a 'freebie' and it does take some time and effort to earn that amount. It would be much less effort coding wise than adding the tickets as a different purchasing agent for the Devs too. Since the three upper level Champions provide double the reward for completing their five levels, that can easily be accommodated with additional button(s) that double the amount of tickets required. Also make the buttons active only when all the rewards of every Champion have been received (the girls, outfits, backgrounds, etc) and all you get is the generic orb or kisses at the end.
Now there's a use for the tickets other than the Champion play which is worn out for some of us players who earned everything and you get the same reward as for playing through all five levels for that Champion. Make sense?
