To me gold and plat are not high because that’s still in the realm of like… completely transferable skills from a completely different game like League of Legends. You don’t even need to be able to aim well so much as just execute basic strategies and look at improving your own play. For example I started reading this post without context and just assumed it was about Overwatch.
Not saying I absolutely agree with that post, but while we’re still in the ballpark of “you can continue to advance by just having common sense”, not even specific game knowledge or mechanical skill… then we’re still playing casual. There’s no reason to get red faced frothing mad over your insta-lock genji player or whatever.
