I think I know why attributes don't seem to have much effect.

[Physic]

Removal of physical level is in 1.19, and it can't come soon enough (as long as it means that stats actually make a difference.)

i think you will be half dissapointed, i think it will make each stat have a specific greater effect, and they wont have to use stat caps, unless they want to, but i think dlevel will remain as an overal multiplier of dmg taken and dmg done to targets. but we shall see.
