Notes

• Update 8.2 (2013-06-28) changed Streamline mechanics to be a linear reduction in cost.
• It is possible to hit the hardcap of 175% Ability Efficiency thanks to  Fleeting Expertise. All Ability Efficiency added beyond 175% is not represented on the UI, though may benefit channeled abilities if your duration is below 100%.
• As this is a Ability Efficiency mod, it will not lower melee channeling costs.
• There is an unreleased Primed version that increases Ability Efficiency up to 55%.
