I mean yes, but the problem with him was stated as a lack of communication (specifically WITH the team... aka just doing what the team wanted because communicating TO was not enough. Just stating your intent (and not budging) was not deemed communication). A Lack of communication on his desire to play off meta... and that's why he was banned. To me, saying that you have to communicate to play off meta and that's why you're getting punished... might as well say you're banning them for playing off meta. Those conversations are going to be highly prone to anger, frustration, and toxicity because it's going to boil down to your team wanting you to play meta, and you not wanting to.
tldr; I still try to warn people since that story started with someone not playing meta as the catalyst of it all regardless of how Riot tried to spin it. I am NOT trying to be a dick (probably comes off that way), but just trying to voice it... which I should have probably responded to the OP in that case.
