I understand, but he won't ever be able to use all 10 attacks. He may have 10 listed, but only get 4-6 tokens (I haven't decided the exact number yet). Besides, this is not something meant for every figure. It should actually be quite rare that a figure needs/gets this treatment. But I thought for the Mandarin, it was worth it. His entire defining characteristic is the ten rings and making a custom of him without all ten seemed "off" to me. It would be like making a Superman custom and leaving out the Flying ability. You can leave out some of his other powers, but he's gotta have flying.
But I understand what you're saying, which is why I wouldn't recommend making most customs this way. It's a special case suited for only a few.
