Simplified weighted dice mechanic

This is a simplified dice mechanic using standard d6 dice to balance 5 unique weighted distributions.

Define the following events:

A = {6,5,4,3,2}
B = {6,5,4,3}
C = {6,5,4}
D = {6,5}
E = {6}

Meaning event B is rolling a 3 or better. The probability of event B is 4:6

Weight each event as:

A(12) B(15) C(20) D(30) E(60)

The weighted events have an average value of 10. If multiple dice are thrown, the weighted average will be 10 times the number of dice:

The dice mechanics are balanced in that each weighted event will on average produce the same value. This makes for an interesting battle mechanics. An example of a balanced battle mechanic is to assign an event to each player. A player's starting hit points are the respective event weight (ie: playerA starts with 12 hit points). Each player rolls a set amount of dice and scores a hit for each die conforming to the event:

PlayerB rolls 5d6 and gets {3,2,5,1,6}. PlayerB scores 3 hits against their opponent.

In such a battle, each player has an equal chance to win. PlayerA, having a 5:6 hit ratio, will do more damage. However playerA has less hit points. PlayerE has a poor hit ratio 1:6, but very high hit points.
