I get so exasperated over how many players just have to make their characters always prepared, always unfazed, and permanently tougher-than-thou about everything. Even characters who are consummate badasses can have moments where they get caught off-guard, and 90% of those I see played like this aren't that.

It makes trying to play someone chaotic or disruptive into such a shitty experience. Or just playing someone who's capable but not perfect, since they end up surrounded by people who are always on point.
