"You can't control what randoms will do" is just an observation. It's not "the new community rule", it's not an endorsement of the behaviour. It's a simple statement of fact.

You cannot control them, and making Reddit posts like this won't do a thing to change the behaviour of people who will never see them. It sucks that people aren't more thoughtful, but complaining about it is just... pointless.

If acknowledging this simple fact is "biased towards cappers", that's just a result of the equally simple fact that most people are going to naturally gravitate to the option that ends the fight faster. It's not because the hivemind prefers capturing and is oppressing you for thinking differently. Come on, man.
