Tl:dr - Add clipping/ collision to enemies (ex. Bandits) to improve 1vX PVE combat.
I don't expect Mordhau level combat, but there are some things in the melee slasher genre that should be done well when it comes to PVE. Below are three short videos that collectively provide an understanding as to why it's important to add collision to enemies. I believe fixing this would add much more depth to the PVE combat.

Bandits bodies phase through each other and even phase attacks through walls that are solid for a player. It looks messy, cheap, and reinforces cheesing. The PVE combat lacks any need for engaging field movement.
Mordhau
Take notice the AI aren't phasing through each other, their bodies are piling up against each other on the stairs, which also spreads them out. This is better because it creates a sense of positional depth to the battle. Also enemies can accidently hit each other if within hitbox, but don't cause team damage.

This clip is from Strat Gaming because he did an excellent job showcasing this.
Do it.
