I must be drunk because i swear i see at least 1 tank support per game, and if i'm not the one playing support then it's usually 2 per game
Soraka is good, but Morgana is not that good anymore, same as Janna (probably? not that sure), not quite sure for Nami but i think she's quite good.
So when do cancerous Blitz/Leona/Nautilus move to toplane?
Their only existance plagues botlane.
Karma is unplayable trash that only Lemonation plays (and no wonder he's not that good), Annie is quite meh.
But the whole point about this post is that if a non-tank support sees plays and success (be it in yoloQ or competitive), they are instantly nerfed: this is not the case for tanks.
Janna still sees plenty of professional play. Nami not so much anymore but I'm sure we'll be seeing more of her come Worlds. She was all over in Season 4, and her nerfs were relatively minor and made to cut back on her safety.
Also I'm not saying Karma's good, but she's seen pro play and she's seen use in solo queue as well, not exactly putting weight on your "tank supports are the only supports in the game for the past two seasons" argument. She also hasn't ever been directly nerfed-- Riot just tried to make her a stronger support with... interesting results...
Considering Janna had an insane pick rate in early season 5 and preseason 5 even, and she forces disengages like no one's business, she's seen some amounts of nerfs to try to curb her engage potential and force weaknesses rather than gut her strengths. Morgana's been nerfed too because she was pick/ban on every level of play, not because Riot has a tank bias. There's a reason Victorious Morgana was brought in. Bot lane in season 4 basically became "Pick/ban Morgana or anyone who can play against her." She's the most-banned support in the EU LCS this year alone. It was incredibly deserved.
Do you not forget that Leona's been nerfed too? Hell, Leona forced a change of an entire item. Doran's Shield start used to be viable bottom lane, and once it was revealed that it was dominating the scene, they changed it so that it was less reliable and then buffed Spellthief's Edge and changed around Coin and Relic Shield. Her passive got nerfs as well, as well as her bases on her W. She's not as tanky as she used to be.
Thresh has lost AA range, shield targets, he's had various other nerfs that I can't remember. Blitzcrank's W slows him down now, and his mana costs were already quite high.
So, no, OP, you're wrong. Objectively wrong. And those tank supports you listed can go top lane when Riot gives them any amount of laning ability at all.
