I wouldn't call them minor tweaks really. Especially turning Clobber into a major damage power as well as a stun; suddenly Mace got a hefty jolt in the single target damage department.
Yeah, WM went from the gimpiest melee set to a contender. It was always OK in AOE, but lagged significantly in single target. With the adjustment to clobber, and the reduction in animation times on some of the other attacks, its single target ability was increased markedly. Then the switching of the target cap of 10 from shatter to crowd control made for a huge upgrade in actual AOE performance.
Too many alts to list.
