What does zeus mid contribute that makes him good right now?

Trying to understand this hero compared to say Puck or any of the Spirit brothers in mid.

So the strength of zeus is he can help sidelines without even walking to a sidelane, by using his ult. If you want to actually rotate to a sidelane, I'm pretty sure puck, storm, qop, void spirit etc are all better than zeus at rotating to gank.

So to use this strength of zeus you want to sit in mid lane. But wtf does zeus even do sitting in mid? He can shove the lane, but he can't jungle efficiently after shoving the lane. Zeus meta build right now is max Q and Q is very mana inefficient for the damage it deals so zeus will use up his whole mana pool to farm two small camps which sounds stupid to me.

So zeus shoves the mid lane. Then he either:
1. Holds his dick and does nothing and goes afk until the next wave comes
2. Jungles extremely inefficiently wasting mana (if u wanna farm pick TA or Alc mid, not zeus)
3. Rotates to sidelane for a gank in which case you shoulda picked puck, qop, storm, void spirit, ember spirit etc all of which rotate and gank better than zeus

Zeus also can't pressure the mid tower like death prophet or dragonknight or other mids can. He doesn't dominate the mid lane like viper or huskar.

WTF DOES THIS HERO EVEN DO, please help me to understand from a high mmr perspective
