Maybe there's a point where an enemy takes enough damage with your gun that it's impossible for you to fail a melee attack?
In fact, if you inflict enough sustained damage to an enemy it will react and won't counter your melee attack. Different characters need a different amount of sustained damage and different weapons apply a different amount of reaction.
For example, Alicia's
Novera CC1-1212 is a light shotgun with high spread that applies a lot of reaction with each shot. In turn, its damage isn't as high as other weapon's.
Is this her intended playstyle?
Each one of us has a different playstyle for each character. I enjoy her mobility by walljumping, shooting while in the air, then melee when landed (her card
Impetus works really well for me).
If I can't walljump, I shoot a couple of times, then try to flank the enemy, shoot again and melee if needed (like
pew, pew, move quickly, pew, pew). Or maybe there's a lot of enemies and I can't get in melee range safely, so I try to make use of her shotgun's spread and hit several enemies at once.
That's how I play, how do you play?
