@WookieCookie: You would ban Junglers if the meta was 2-1-2, for failing to communicate "with" teams
For those of you looking for the background, here - http://boards.na.leagueoflegends.com/en/c/player-behavior-moderation/FrILlWp7-14-day-ban-because-playing-nunu-support-with-smite-is-stealing-other-peoples-roles?comment=00f0
When you start out playing League, lane assignments are pretty straight forward. 2 Top, 1 Mid, 2 Bot.
Suppose for a moment that 2-1-2 was the meta from Bronze 5 to LCS, with "Jungle" being the top lane Support that took Smite so they could kill Baron. How would you communicate "with" your teammates to consistently go our normal Jungle position where you abandon Top in a 2v1 situation and "AFK in the jungle"?
You know why the strategy of having someone farm the Jungle is better overall, after all, you invented it (in this scenario). But you've got to communicate the Gold/Experience/Objective Control/Pressure on Other Lanes advantage in a convincing way over chat to a disbelieving team in a time span of about 2 minutes. And you've got to do that every game.
Who's going to oppose this change the most? Your Top Laner. You're leaving them in a 2v1, and they just know they're going to get pushed under tower and dove over and over again, and you can't get much gold or experience when you're dead. Your other teammates are skeptical too, since you're basically avoiding the enemy all game. You get into game and you want them to come help you get started killing monsters?
I have no doubt that if we were in a 2-1-2 meta your system would pick up people trying to go 1-1-1-2 as a ban worthy offence over ~200 games. They'd be jumped straight to 2-week ban and threatened with a permaban. You've said that won't happen, but we've got two instances of a support person threatening players coming up with new strategy with permabans now.
You say the key is communicating "with" teammates in champion select, but no one is figuring out how to do that consistently? Show us an example. Video record a lobby in this situation where the Top laner is adamant about sticking with 2-1-2, and you're equally adamant about 1-1-2-1, and show you communicating "with" that Top even if they are communicating "at" you. Show us what it would take to play your strategy without being banned.
