It's been a while since I've done a comprehensive Player Behavior post, so here's a shot at one of the most discussed concerns right now - Singed Support and other off-meta picks.
I'm not going to leave you hanging; no, Singed Support is not banable, and going off-meta is not banable. What is punishable, however, is refusing to cooperate with your team. And I'm not talking about muting other players because they're toxic or because you don't want to tilt yourself, but rather a refusal to ~~explain what the actual heck you're doing to your team and subsequently work with your team to carry out something that they aren't used to and/or comfortable with~~ work with your team even when they are uncomfortable with the position that you're putting them into.
Allow me to explain further. I like to go Swain Support. It gives a good return on value and allows you to steamroll their marksman at level 6. During champion select, I explain that I'm going to go Swain Support and we're going to be an aggressive lane. We enter the Rift. This is an example of playing off-meta (and is hella dirty; give it a shot sometime maybe). Picking the "Support" role, I know my primary responsibilities are to protect my AD carry (death is the best form of crowd control) and to ~~shut down their bot lane~~ control the lane.
Let's pivot to Singed Support. I've done it once. It ended up badly, but I made it clear that I would be playing Singed Support, and I played the role the best I could. Playing badly isn't against the rules, but refusing to play the role is another story. Had I gone smite Singed and just left my AD carry alone botlane AND our AD carry didn't understand that I was going to leave botlane for 5+ minutes, that's another story.
I'm going to wrap this thread up by quoting the Summoner's Code and asking you to put yourself in the AD carry's shoes. You're in series to promote into Platinum, and you see a Singed Support. They tell you that they usually top, and when they get support, they don't spend the first few levels botlane. They don't give you a choice but to comply or dodge. You can't dodge, and he seems pretty confident. The match begins. You're trying to farm, but the enemy botlane is harassing you hard. You're zoned off of the minion wave, and you become irrelevant fast.

(1) Support Your Team
> Being a good team player begins at champion select. Be open minded when considering the needs of your team. If you're the last one to pick, try to fill a niche in your team that hasn't already been filled. If everyone's picked and something stands out as a deficiency in your team composition, try asking for another player to fill the gap, or change roles to embrace that responsibility yourself. Remember, that by taking on a role you don't normally play, you'll learn more about unfamiliar champions and increase your own skill level.
(4) Enjoy Yourself, but not at Anyone Else's Expense
> Once communication breaks down, the likelihood of victory is drastically diminished.
There are clearly a lot of opinions on this topic, so if you'd like to contribute to the discussion, don't hesitate to drop a comment below. I'll be checking in throughout the day, and hopefully we can try to understand where each of us is coming from. Cheers!
