Why are people calling it “casualbringers” now?

I’m still of the mind that these “bad players” should actually put forth the effort. I disagree with bringing down the ceiling to meet them because they simply don’t want to try and get better. It’s catering to laziness and positive reinforcement of poor play.

I get that, but the problem is that's not happening and the same complaints about bad players are still happening over and over again, devs read this on the forums thus try to make it so there are less bad players, so from a development standpoint what needs to be done?
