One of the things all three playtesters wound up begging for in unison pretty quickly when we got into discussing what worked and didn't in our playtest was a cap on The Pool. 10 dice, they said. 10 dice was a great number. Don't mess with it. Take away from it for injury if you like; that's okay, but please, dear G-d please, no more. Between endangering dreams, seeing your dreams in actual harm, and acting according to your ideals, you could wind up with a mountain of dice. Mountains of dice are nice in theory, because everyone loves powerful characters, but in actual play mountains of dice suck. They're too much to manage, and the game becomes more about moving dice around than playng the game.
Please, Cliff, they begged, keep a hard cap of 10 dice for The Pool, and find another use for all that other stuff.
A rough rule I've picked up for evaluating playtest feedback is that if one person says something needs to change, but the other two seem not to care, I'll make a note about it but won't necessarily do anything right away. If two people seem to think there's something wrong, however, it needs to change. When all three agree there's a problem, it's a big problem.
Thus, without any further hint of consideration, there's now a 10 die limit on The Pool. You don't add to it. Nothing grants bonus dice. Maybe some things can grant bonus successes, meaning it's still possible to score more than 10 successes in a single roll, but you will never have more than 10 dice in your pool. Ever.
