limiting the dice pool size

I'm thinking there should be a limit to the number of dice that you can throw at once, I know that kinda defeats the purpose of the dice pool system, but I noticed that in shadowrun, the lack of a limit, sorta broke the game, cuz you could throw like 40 dice when you only need two successes, making failure nigh impossible. So I think the max pool size should be determined by the total number of points allocated on your progression trees. So if you have 4 points in honesty, and 8 in friendship your dice pool size is 12.

The number of dice you roll for a skill is determined by the number of points you have allocated into the progression tree plus the modifier of the relevant ability, declared by the skill. so say you're using a skill that is dictated by the friendship element, and is modified by the wisdom ability, and they are 8 and 6 respectively. so pre-pool limit, the number of dice you would throw would be 14 but say we're using the pool size of the character above, it would be cut down to 12, and would remain like that until you get more points for progression.
