Really? I've not ran below 670SS since A4S and I've rarely ever encountered Thendiels "Deadzone" and that's with Selenes uptime at 100%. Do you use IR -> BOTD, or BOTD -> IR in your opener? I've switched to the latter and it just feels so much more fantastic.

Talking of low SS, I will say, cooldown alignment is definitely "better" to some degree. Life Surge procs with Full Thrust more often and delaying the 2nd BFB by a GCD (So using it after True Thrust), reaps really insane PPS benefits, over using it before the Phlebotomize (As long as the BFB is delayed). Delaying it this way, pushes the 3rd BFB to after a HT, which again, gives you really high PPS benefits, purely because of the interaction with Jump and BFB.
