I’m fairly sure on a public forum there’s no requirement to justify why and whose I respond to posts.
You were suggesting being shut down on a hero and not switching saying “It’s just QP” isn’t an acceptable response. I’m pointing out that actually it is an acceptable response and why. i.e. that you’ve no idea who you’re speaking to and what understanding of the game they have, and there’s zero requirement for people to learn any of the tactical stuff - and in some cases they may not even have the capability to do so if they wanted to.
If they’re doing that in comp, I would have more sympathy (although even then, there’s nothing saying that you have to have a certain level of understanding of the game to participate) but it’s a game for people to play at whatever level of knowledge and skill they have, and there’s no requirement to improve or reach any certain level of understanding, especially in QP.
