I think that Guillotine Fist should have the cool-down reduced to 20 seconds. The duration of Fury should be reduced to 10 seconds, and the cool-down should be reduced to 10 seconds. This means the duration will be 10 seconds, and the cool-down will be 20 seconds (technically 10 seconds, after the Fury duration ends). This would at least allow us to use our finisher more often.
Having to recast Fury all the time would be a pain though, and cut your DPS by making you waste spheres. I'd think it'd be better to just lower GFist's cooldown to 30-40 seconds, so it'd still be usable only once per Fury (possibly twice with 30s, but with only a small window), but would give the Monk more flexibility in when they can cast it.
