Yeah, that's why I try to have both a ranged and a melee weapon in my arsenal. My End-all arm is heavy and loses to most other melee weapons in a melee clash

. I think I'll fuse it away because I just can't beat other melee people with it, even though the arm can OHKO anything without defence boosts.
I often alternate between a ranged/melee weapon because the stages tend to alternate between narrow and widely open too.
