That’s funny, my friend loved hammer in world and he vehemently hates it in Wilds. I don’t ever use it so I don’t have an opinion but it’s funny how some people love and hate the same weapons.
I can probably pin point why he doesn't like the hammer in wilds.
Slope rolling attack are harder to get and do less damage, before when i saw a slope it was spin to win time, now i almost prefer bonking normally because the characters take a while to enter the slide state, the number of spins are lower and the damage seems to be lower.
Before you had 2 sets of attack because you had the power state that change the moveset and now it is gone, rise had even more stances.
The big bang attack does way less damage so it is not useful anymore, unless you just love the animation, sometimes i just use the 4 small bonks to get into the new charged move but it is not ideal.
The style now seems to push you into using the new charge move as much as you can making the gameplay maybe less varied.
Hammer definitely feel more fluid and the move with circle to get away or close distance while keeping the charge is a godsend but some things were better in world\rise hammer.
I guess that many people have a favourite version of a weapon and it's hard to get used to a new version, i was a lance main in world and absolutely hated the lance in rise with its stupid ass charged slap style and wirebug moves that were everything but precise (and lance users love precision).
