The champ is flexible. You don't need to limit yourself to a certain build-path. My core item build is Mallet-Liandry's-BORK, everything else is situational. My main focus is denying the opposing top laner (since it's what teemo is made for). I often end up winning lane and group to end. I don't consider RH to be one of the key aspects of this build + I already said how I don't like it.
