Improve Weapon Damage

[Kaiser2]

Ok, I was thinking, and something struck me. Improve Weapon Damage severely unbalances weapons with varying attack powers. For example, take a dagger, it has low attack power, but it is VERY fast. Now, add 10 IWDs to that, and compare it with the sluggish inferno sword of 10 IWDs, NOW which weapon is greater? the dagger of course, because at that point, a few measly little damage that made a big difference in the beginning makes no difference now. IMO, it should be changed to this:
Every IWD adds damage based on the original attack power of a weapon, like, 1/2 of the original attack power, that way, an inferno sword with 10 IWDs would have an attack of 60, whereas a weapon with attack power of 6 have 36, instead of 56, makes more sense, doesn't it?
