Well since MNK will have Chakra and Invigorate, our endurance will drop comparatively. I guess DRG was a bit unique in that we could get a few more actions out due to 500TP Invigorate.

Also as an aside, using the various dps sets in your list Dervy, i think most of them have <390 skill speed, or am I mistaken? Is the 9 GCD during b4b overrated?
