Machinist is almost the same but not quite, their play style is still stand-still but I -think- they get more abilities than we do which allows them to insta attack more in stance but I'm not positive so yes, machinist would probably be preferred more over a bard still learning the proper rotation for WM if that's the case.
Have you tried swapping though or do you just leave it on? The thing with WM is that you swap, not leave it... like I said, you are losing extra attacks with it completely off all the time as well. Each bard is probably all using different rotations too which would give different numbers.
