ARAM Jhin
In ARAM terms, Jhin is the most obnoxious parts of playing against Teemo (traps), Lux (idiotic snipes on a low cooldown), Fiddlesticks (high-damage, unavoidable harass), and on the linear map of Howling Abyss his ult is basically just four Jinx ults. Plus, he's an ADC, so he can push towers, and he chips them better than any ADC except maybe Cait. On Rift, he's fun and fairly balanced, but on ARAM he'll quickly be welcomed into the 'SMH tier'.
