Agreed, MNK is kind of the top single-target DPS already, and for the most part probably needed little if anything changed.
Far as WAR goes I don't think it will affect much overall, they may be reducing SS ability to hit as many targets and reduce the amount of damage done with Rampage up, but they're making it easier to spam on a whim with the reduced TP needed. Case in point Garuda I'm always saving up 2k TP to throw out SS whenever she warps just in case doesn't get close enough for me to start off the combo before she summons plumes. Without the need to save up as much TP I can start throwing out more WS moves between rounds and actually take her down faster, so damage really isn't being hindered all that much in my eyes.
Aye that's what it sounds like to me as well.
