Jesus Jax is dumb, you get so many free stats just from your kit you're free to do whatever you want
You don't even need Conqueror to faceroll someone, it just makes his all in potential higher, but really you don't even need that.
I'm taking Fleet Footwork right now and just farming up with the sustain until I can brainlessly E+Q+W combo everytime the enemy blows a CC. I just chunk them down bit by bit until I can hit my R button and ignite them. And even if by some miracle you lose you just have to go full Split-push bot, the enemy can't ignore you doing that or they'll lose 2 towers in 2 minutes.
This champion is not hard, you actually have to be a complete moron to fail on him.
