I have just updated my SCI build on my Luna class and I have two Deflector Doffs that reduces the cooldown for Energy Siphon and Tykens Rift.
I use Energy Siphon III and II. When I mouse over Tykens Rift I see that the two Doffs will reduce the cooldown but I don't see that on Energy Siphon so the question is now does it work or is it buged.
I belive this was broken some months back when they removed some shared cooldowns between deflector abilities so that we could use different ones at the same time. As far as I know this was never fixed.
Please correct me If I am mistaken but I think deflector officers only affect tykens rift and gravity well now. I know they certainly don't help energy syphon any more.
