The problem with off-meta picks and Singed Support:

There is none...

...in Normals.

When you play Ranked, you are competing for chance to get to Challenger, get noticed for your decision making, mechanics, CHAMPION CHOICES AND MASTERY and ultimately make it to 'the show', aka LCS. There is NO other reason to play Ranked other than taking the game seriously enough to want to be a professional. Normal play and Custom games are where you can "play for fun" and "play casually". The fact that you are not aiding your teammates in winning the game is negative behaviour. Your champion select picks should be based off 3 things in Ranked:

1. The bans that came through.
2. The enemy team's selection.
3. Your team's composition.

If you refuse to pick your champion according to these guidelines in Ranked then you should be removed from the Ranked ladder and forced to play Normals, where you belong. The counter argument I anticipate here is "No, you should be playing your best champion!" -- No. Sorry. You should not be playing Ranked if you are not comfortable enough on a range of champions to meet these three requirements above.

Please, play Singed Support, but do it in Normals or when it fits for the 3 above mentioned requirements.

Props to Riot for addressing this issue. I do not think banning the player is the right course of action, however, Ranked restriction definitely is.

Thank you.

P.S. I will consider the amount of downvotes as trolls. Riot, here's an easy way to find targets to manually audit. ;)
