I will reply since i am always interested in new mods i haven't discovered that still fit with the game's aesthetic.

I will say some classes i have on and i like:
- The Steel Driver, he is a frontline class who is rather bulky, has an armor piercing move, can increase his PROT, self-sustain. His design is why i immediatly searched him up. He is what i would expect if they added a DLC hero for the COM dlc. Very usefull in the Farmstead aswell due to increased dmg against Husks.

- The Bowman, maybe he is on the more OP side. Very simple abilities: He does A LOT OF DMG, he is best used on position 4 only, has only abilities for the sake of damage but a notable ability is a TOGGLE he has (the toggle does not take a turn and let's him switch between armorpiercing, blight or bleed). If you can you should look up his workshop since he has been adding a few classes recently (Bowman, The Owling, The Hexer). Due to his kit, he really can not do much at all if he gets shuffled.

- The Templar, he may not be the flashiest in movesets but i like him as a comfortable member in my quests. He is a tank for position 1 and 2, who can support by slowly stripping PROT with one of his common moves, has a heal based on percentage hp that has a cooldown, can guard allies and also has a move that can reflect damage. Just a tanky protector but since i do not have many classmods that are healers (i only have him and Homunculus) i like to use him frequently.

Milkmaid, she is pretty much immune to bleed, but has low blight resist and health to balance it.
Comes with a custom disease that makes her immune to other diseases and get no effect from food, both not needing it but also not healing from it.

Slayer, if you want one with pretty much normal stats and mechanics all around, mainly supposed to be a frontliner but can be a viable backliner if you have another backliner that moves themselves back.
