Cooldown Reduction Continuity and Clarity

Math lover here.

I would like to see a consistent representation of CDR whether it be positive or negative. Specifically, normal and scaling CDR are negative for glyphs, but CDR is positive for the Intelligence mastery, for instance. The runes do say - X cooldowns, while mastery is + Y CD reduction, but it would sure help the whole 'for the sake of clarity' movement!
