Blah blah blah words.
You basically implied it, so it's w/e. We're balanced around backloaded damage, and frankly, that's fine. We can still do more than enough damage to compete with the middle/lower top end of the pack on single target, and then blow them away at execute. Fury is fun because of execute, for the most part, and gimping it this hard is just retarded.
As far as burst phases, fury is a burst spec. It's CS -> conserve -> CS -> ad infinitum. Proper rage management is the skill cap of the spec, and frankly, the current model of it is perfect.
But in the end, unless arms roundhouses fury into the next expansion, I'm not going to switch. Arms just isn't fun, with fury there's planning and rage management and forethought into what you do. With arms it's just MS -> filler, with your next ability being a short priority list, mostly based on how much rage you have. That's not fun.
