Kalista or JInx

kalista if you want broken hands and to have people hate you

she needs a bit of practice though

Jinx is easier and for solo queue, I would say they both give about the same reward so I would say Jinx. For ranked 5s, Kalista ult becomes easier to play around since you know your support but it's really tough in solo queue

It's not even a question! [slayer-jinx-catface]
