If someone apped say, Deku from MHA into a game and didn't want to tag Bakugos and opted out of it, nobody would bat an eye. Same if it was reversed. That's why opt outs exist. The people you're replying to even say that it's in "bad faith" to not tag castmates as the onus of this conversation and you're the one who brought up how it would be weird to even think about not tagging a castmate.

Only WoL players feel the need to think this is weird and upsetting, so I'm going to assume you're a WoL player that's salty people don't like you in this thread.
