At least part of the idea about the release structure is about the value. People paying for a toon, regardless of what anyone else thinks about their usefulness, are being given a "set value" for their investment.
I would imagine that part of the reason we see all toons hitting marquee events and following the same release structure is to keep that even, but to also not show a "judgment" on any 1 character vs another. They all have their uses and not everyone is solely focused on arena.
