Is this parody?
This has the side effect of vastly improving role-playing, because you can now play a character with a 1 in an attribute.
This has got to be the strangest instance of Stormwind that I've ever seen.
For hitpoints, just do some simple math. Barbarians get d20-8 HP, and wizards get d20-16.
So ..... negative HP is desired as a potential outcome? (wizards would be losing, on average, 3 levels worth of HP
per level)
Either divide the die; or (perhaps you meant to add this) ignore results >"x".
Combat is simplified. A dagger does d20/5, while a greataxe does d20*3/5.
Wait ... multiplying fractions on the fly (as opposed to adding whole #s) is simpler how?
Magic is also a lot simpler. Normally, casting Disintegrate at 20th level requires you to borrow every d6 at the table until you find 40 of them (which means that, in some groups, you can't cast Disintegrate at all at higher levels!), and then roll them all at once, and painstakingly add them together. In the new system, you just roll your d20 forty times, divide each roll by 10, add them all together, and multiply the total by 3.
If simplification is desired, wouldn't just "taking the mean" be simpler? 30+ dice invokes the Law of Large Numbers; so taking the average is empirically and objectively justified. Hell, a threshold of
10+ can be
perfectly justified
