I would say go thresh support. Throw lanterns and take control of the bot bushes. If you can get a good throw to know back combo on their adc, any half-brained adc on your team should be able to burst that sucker down for a gg.
Try going with an unconventional support. I've been doing Lux and GP supports a lot more because I can transition into something else if necessary.
I play Morde support with Nasus ADC bot all the time, and it wrecks.
Can't do it in ranked, though, people ragequit.
They might ragequit because they think that they need a support that can better defend them or can otherwise bolster their own power. That's why I suggested Lux and GP. Lux has a decent amount of early game burst assuming you land Q and an auto. GP pokes well and can get some gold from that mastery in the support tree. GP can also transition into a late-game monster if necessary.
Are people the dominant race or are they just overly self absorbed?
