[1.2.322] Moar Skill Balancing

Excusing my ignorance, how exactly does it work out that way? Wouldn't 200 watt be better than 150 watt (150 resulting in a 1.5x multiplier while 200 results in a 2x multiplier)? Why would magic attack be any different?

If a Hero has 200 weapon attack, +20 weapon attack is +10% damage.

If an I/L has 320 magic attack, +20 magic attack is +6.25% damage.

Assume that both classes would do the same amount of damage before even though their attack values are vastly different. The reason mages have a 0.88 multiplier is to compensate for how high their magic attack naturally is.
