I find the dwarf one handed hammer to be an extremely fun weapon to use however I find the last two swings in the combo to be an issue. For a weapon designed for crowd control the last two swings are both vertical which leave you completely open at the sides. This leads to a lot of padding by constantly push shoving mid combo to keep the cleave going or resetting with a block. This artificially reduces your weapon speed and causes you to be doing less crowd control than you should be doing unless you’re in a very narrow chokepoint.
I think the weapon would be better off if the third hit in the combo was another cleaving attack with the last hit remaining as a downward strike. This would make light attacks much better off for crowd control without need to spam shove attacks to compensate.
