[gameplay] Jax E bug?

When in game, even though Nasus his Q is defined as "Nasus empowers his next basic attack within the next 10 seconds to deal bonus physical damage." Jax cannot stop the nasus Q with his E. So either the tooltip is wrong and Nasus' Q is a spell, not an empowered basic attack, or Jaxs E should block the Q. If I remember correctly it used to do so, but not anymore, in which case Jax has not even the slightest chance to ever dueling it out with a Nasus. Can you please look into this?

With regards,
