This item has actually become an important 3-4th item on many many heroes. Heroes that have -X% cooldown on their trees benefit more form Octarine than ever. Since cooldown reductions stack additively, it has made a lot of abilities far more powerful. Batrider has infinite flying at 25, techies has 5 second cooldown mega range remote mines that do 750 damage, and the list goes on. I'm half expecting this item to become very popular, and possibly nerfed to work multiplicatively.
