Well, last I've heard from EVERY source ever, you need to reach a minimum of 400 skill speed to optimize your combos. The previous best in slot setup was over that mark as well.

This is definitely not the case.
Twin Snakes is 15 seconds now not the 12 seconds it used to be.
You never needed 400+ GCD to get 6 GCD in 12 seconds for buffs because of the delay between skill activation, skill animation and skill application.
The BiS gearsets never took into account a minimum Skill Speed.
