+Spell damage vs +Chance to Crit Items

[Tommi]

+dmg is very effective for spells that have low initial damage and relatively long casting time, but which are improved through talents. +dmg has less effect for spells that have relatively high initial damage. Thus, the effect of +dmg varies from spell to spell. In fact, it is very useful for low level spells, while being relatively less useful for high level spells.

This is the problem, when game designers use straight +damage modifiers, instead of % modifiers, such ED% in D2.
