Seems to me that a reduction in the number of worlds isn't good business. HBD isn't big business. 32 owners. Assuming they make $15 on each team at rollover(very generous considering credits, discounts and bundles), $480 each new season. There are 168 worlds. At best, they average 3 rolls per year. That's less than 250k a year. Then you have to pay for operating costs. FOX might make 100k per year when all is said and done. That's hardly worth keeping open.
And it seems that you're more than help them reduce that 100k.
Doesn't make much sense to add a feature that will help reduce the meager profit they make now.
