It's funny to come back and re-read everyone finally come to the realization that:
1. Having DoT's in your rotation will drastically increase your DPS.
2. That you're a FOOL if you don't include Fracture.
3. That they can be used (bosses) without losing any of your buffs. (Dragon Kick Blunt decrease, Greased Lightning 3 + Twin Snakes damage increase)
4. That Skill Speed actually does matter
and last but not least, that Global cooldown is NOT 2.5 sec at level 50. If it is, you really need to re-asses your gear.
With greased lightning 3, my GCD is 2.02 seconds. I am able to get 5 full moves off before i have to re-apply greased lightning 3 with Rockbreaker, Demolish or Snap Punch....whichever the situation calls for.
With a SCH in the party giving you the 20% skill speed buff, your GCD can be well below 2.0 sec (1.90 for me currently BEFORE i purchase some AF+1) giving you another move to rotate in the process, not to mention your 2 instant abilities, Howling Fist and Steel Peak (save for when needed).
Be sure to bring over Impulse Drive from LNC which, if dealt from behind, delivers a whopping 180 potency every time. Also, it doesn't affect your fighting stance either.
Just thought I'd like to share. Keep on out DPS'ing the DRG's and BLM's.....HA.
