I think it might be a tie between Karma and Sona. Karma isn't very popular so I don't have a lot of experience to speak from, but her kit just feels a little underwhelming. It seems like it's trying to be the jack of all trades and therefore falls a little flat. On the other hand, I used to really like Sona, but now she suffers the same problem as Karma. Not to mention if the player isn't being smart, her fragile base stats do not help.

 

Twisted fate and lux support
I know the idea might be appealing because you know root and stun, but by god if they waste their cc poking they cant do anything because they are squishy mages and there is always that moment when tf says and i quote " u fcking piec of shite let me farm with m blue card i carry u nabs"

 

Ironic comment with your avatar.

Personally I dislike seeing the melee carries assupports, poppy fiora, tryndamere, etc.

 

I dislike Thresh supports. Everyone I get at my elo all seem to be first time threshes. They never get their hooks. Once they do get a hook, they type in all chat MADLIFE and get killed.

 

I'm happy to play with most supports as long as they have some lane presence, but am hugely tilted by any support that plays back and doesn't contribute anything while the enemy support/adc 2v1 me and zone me off farm / poke me out of lane. Or full AP supports that build no sightstone while we get ganked and roamed on from midlane every other minute...

 

Blitzcrank. If you cant win early game you're more likely to fuck your team over with a missplaced hook rather than help them.

 

I don't know why, but I've never really liked Janna support as much as the others.
