I feel like that is the only "fair" way to do it.
As mentioned earlier by , subeta's birthday should be for everyone to celebrate. There shouldn't be these ultra rare prizes that only people who are really into one small aspect of the site get an actual chance at.
This would let the battlers who put hard work into their pets get an easier chance at the prize, while still obtainable for the rest of the user base, for those who want to put the work into it. Battlers already put their hard work in by training.
However, I think floating items should not be done away with. Its pretty much tradition at this point. I'm all for adding new traditions, but not necessarily doing away with the old ones.
Don't get me wrong, I just threw an idea of how to include piñatas in the birthday celebration. Prizes should be the same for everybody, and huge no-no to giving weapons this way. Piñatas only hold candy and confetti, after all. If they were individual challengers I would just stick to the traditional boppers. But seeing they wouldn't work as global challengers either, maybe just make this year's goodie bag a piñata? :P
I would like to see a way to get old birthday items. Some of them are way too inflated. :(
