Dicepool, 5s and 6s success, 1s are tallied for fumbles/complications.
Compare successes to target number or opposed pool. More than half your pool is 1s? Complication. Failed and complication? Fumble. Easily factors in degree of success/degree of failure.
And most importantly it’s a curve that stretches rather than moves. What did that mean? Failure gets less likely but never hits 0. Complications less likely but never 0. The value of adding extra dice to the pool never hits 0, but you often reach a point where you deem it’s good enough to go focus on other things.
I agree with your overall point, but replace d6 to d10 and have adjustable TN's Basically world of darkness.
TTRPG's are not MMO's, you shouldn't be playing just to stack abilities and combos to down the BBEG in record time.
