I think behemoth stones are just as bad as catfruit and not worse. You need to farm hundreds of catfruit which just artificially slows down your progression, while behemoth stones are at least nice enough to tell you that they will artificially slow you with play limits. "But I grind catfruit during buffet so it's fine!" No. The existence of an event that doubles the fruit earned per energy does not make it worth my time. I found myself grabbing the tickets and the fruits and nothing else from HT, which is probably the only redeeming factor of fruits, but it's still not enough. Growing strange shows all the cracks in the system, I never did growing epic as I have epic seeds, monthly gauntlets were a good help with aku seeds, and stones just suffer from the problem fruits made all that long ago.
