I can use the new CB to make characters it supports, but it does not yet support ONE SINGLE character from any game I'm playing, when all were supported in the classic CB. Innate bonuses, DM created magic items, custom feats. Heck, I can't even give a character a net that they picked up because they aren't proficient with it which means that even though they can use it (just sans proficiency bonus), they aren't allowed to carry it.
I asked WotC for a refund for November since I have nothing I can use for ANY of my active games. I was turned down.
WotC has intentionally replaced the classic CB. The new CB has demonstratively less functionality. If I am getting less I want to pay less.
I think this will come together. But until it does, I don't think I should have to pay for it.
