^This thread covers quite literally every point of min-maxing you could hope for with the Job.

To summarize, assuming you saw it and tl;dr'd it:
1. Delay IR/B4B/BL (generally) ~1s into the GCD so you get 7/9/9 gcds instead of 6/8/8 under the effect.
2. 3 gsk per minute, always. After the first B4B, every B4B should cover 2 casts of gsk in ideal circumstances.
3. Life Surge for the next Full Thrust, Fang and Claw (with positional) or Wheeling Thrust (with positional) after LS comes off cooldown.
4. In general, don't hold buffs or ogcd skills for any reason - yes, this includes holding PS+Jump or SSD for the following B4B. Don't do it, it's rarely a gain.
