For me its bad animation.
Specifically how does my character animate while rotating in place.
Most games that animate like this gif have very shit tier animation, which leads to combat feeling lighter than paper, which in turn leads to bad feeling combat, which leads to a bad game
As soon as I move the left stick around 360 degrees, and
this is how my character animates - I get turned off the game immediately. Unless the gameplay itself hits REALLY HARD and makes up for it in other aspects, its going to be hard for me to finish that shit.
In an action game I need good animation to go along with hard hitting combat. This below is just lazy to me. Good animation helps your games combat feel smooth yet heavy.
This makes your entire combat experience feel like lightweight, which is a huge turnoff for me.
