Currently range and duration are both a bit too slot inefficient. And often want to both be taken together, making this even worse.
Compared to superior cooldown, both items work with far less abilities, and far less other items, while often being semi niche even when they do help (do you really need more range on torment pulse for example)
greater expansion is almost never seen, its a bit expensive for what it is
The proposal, drop greater expansion to tier 2, make it give less range (30% for example)
and make Greater expansion an Superior duration build into a new item. Ability Maximiser, a tier 4 which gives 35% ability range, 35% duration, (and maybe some other stat, possibly 15% cast time reduction)
