New Tiamat seems good with a lot more champs now, especially because of the upgrade. Warwick, Volibear, Malphite, Nasus, Riven, Mantheon, Shen, Irelia, Renekton (Active+W), Jarvan, Xin Zhao, Jax...oh god Jax with a decent cleave item. It's gonna be good on a whole lot of bruisers that rely on auto attacks.
What would be funny is if you use your Q with Nasus and kill an entire minion wave, it gives you the bonus dmg for all the creeps killed by the Cleave.
