Do you know that efficiency ISN'T capped at 175%? The EnergyDrain is capped at "at least 25%".

The formula for Energy Drain for channelling abilities is as follows: DRAIN = STANDARD_DRAIN * (2 - Efficiency) / Duration

With some math analysis you can clearly tell, that when you achieve Efficiency = 200%, the formula on the right = 0  (There still is EnergyDrain cap). You can easily check the formula with any frame that has channelling ability (or look it up this wiki) and you will also find, that there are Arcane Helmets that let you achieve 200% Efficiency (like Arcane Chorus Helmet for Banshee). You can then forget totally about Duration ( 0 / Duration = 0).

That's why the DE removed it from Chinese version and that's why DE won't ever deploy it (unless they change EnergyDrain formulas).
