We'll have to agree to disagree.
You often see things in the extreme. I don't see allowing a limited IP contribution to another player (for a limited time) as turning the whole system on it's head, or fundamentally changing how IP works.
I also don't see SBS setting an "unbalancing" amount of IP per token. As an example let's say 100 per token, with a limit of ten. So an individual could at most contribute 1000 to another. Given the vast amounts of IP many Monarchs have, it really isn't that unbalancing. Additionally an individual may decide to help their duke/duchess, or count/countess instead. Or some combination of all three. And all of that is assuming that every individual can afford or wants to spend $100 on tokens.
Finally I'm pretty sure people don't need months to adjust to a token going on sale, but who knows, I may be wrong.
