Yeah the rage nerf is no big deal for DW Fury, but for MS where you really have to make the most of every swing because your weapon is (ideally) slow as hell but connects for a fairly decent hit, it is kind of a big deal. Where you'd normally be able to pick a cloth target, autoattack them for a decent chunk of damage, (hopefully) crit them and use that rage to fuel Whirlwinds and other rage dumps besides MS, Hamstring, Pummel and Execute, now you really have to be a bit more conservative cause you can't count on a decent enough bit of rage off a non-crit swing...and the stakes are really high with how high you have to stack crit rating to rebuild a decent percentage and the inflated amount of HP people have. If you don't burst someone smartly, you're gonna lose a lot of momentum.
