Power Efficiency cap?

[(PSN)daveoncode]

Why by combining fleeting expertise (+60%) + streamline (+30%) I get only 175% in power efficiency instead of 190% (100% + 60% + 30%)??

Is it a desired behavior? Why? Is it the only attribute with an hidden cap?

Because 175% is the hard cap on cost upon cast. It would be silly to have ultimates cost only 10 energy. 

Channeled abilities however take advantage of the 190% efficiency by allowing negative duration builds. Duration can also affect channeled abilities cost so vice versa you can stack lots of duration and lower efficiency and still keep low drain.

Yes, it's capped on purpose.

only as long as its no lower than 100% eff....otherwise it wont matter how much duration you have for channeled abilites...it will drain energy like crazy (looking at a chroma with under 100% eff but over 250% duration as an example)

as stated: hard cap 175% for initial costs.

channeled abilities like WoF will cost less with 190% while channeling
