First things first, revert the recent Killing Spree and Blade Flurry changes. Combat will be ridiculous if those changes go live. Second, if you want to make recuperate useful, make it tick every 2 sec and revert the recent Glyph of Recuperate change.

Well, that's it for now. I'm far too lazy to elaborate the reasoning for each and every change, because honestly, I highly doubt any of my well thought out changes will ever see the light of day. There are so many ways you can balance the Rogue class and this is just one of many and anyone who says this is the only way it can be done, is a coconut. GL HF!
Edit 2: Reworded Vendetta, Burst of Speed, Revealing Strike and Venomous Wounds. Removed energy cost from Burst of Speed. Reduced cooldown to 30 sec, down from 32. Increased duration to 3 sec, up from 2.
