Go easy on the capitalization a bit. I realize English may not be your native language, but try to do the best you can.
I had my firstkill today on Conclave 10 HC and I was on Rohash Platform as Combat Rogue and was able to stay on the Floor during the Ultimate because I used Killing Spree when he hit's 100 Energy. Not recommended when there are Hurricanes in the Middle because they will instantly kill you.
With Grounded Plasma Shield+Feint on CD and not Imp. Recuperate i came out of the Ultimate with 90-100% HP making the live of our Feral Drood and Disci Priest easier.
