They seem to have made D:OS1 cooldowns more fine-tunable in the EE, where each skill can have a custom cooldown reduction. Not entirely sure how the numbers play out (data "CooldownReduction" "40" on BoulderDash, for example, whatever 40 means), but I believe I could eliminate cooldown reduction entirely. I think they already have gotten rid of or reduced high stat cooldown reduction for a lot of skills. Not entirely sure how effective high stat cooldown reduction is, but it doesn't seem very strong so far. 10 Int (I think) only gives me 2 round CD reduction on 10 CD abilities.
I kind of like cooldown reduction as a way to keep novice skills useful later on, especially ones that don't scale, but it does make balance a bit more complicated.
