I actually really dislike this. If characters act unjustifiably stupid, it annoys me and I leave. I prefer characters who try their best, while amplifying their flaws often requires reworking how they’re previously characterized. Even then, if a character is too flawed, I often don’t have fun watching them. They’d need to offer something else if they’re so incompetent. If they just suck, why have them?

I prefer to consolidate allies, only including ones that are indispensable.
