Is maokai Overtuned or broken?

For those who don't know let me explain.

Overtuned: stands for a characters numbers being to high.

Broken: stands for a champs kit being fundamentally broken. And that disregards the usual rules of leauge.

Overtuned Examples: sett in pc when first released was overtuned as fuck. His kit was exactly the same and there were no deviations but his number were simply to high.

All they had to do was nerf his base stats a bit and boom balanced.

Broken example: ksante when first released was completely ass despite his broken kit.

(For those who don't know ksante is a champ that is a combination of a warden/skirmisher. Just think of him like a tank yasuo and yone with true damage. Who has it all dashes shielding damage reduction cc true damage ect)

He was an example of an undertuned character and throughout his entire lifespan in leauge he's been a consistent pick in high elo even when he's been nerfed to the ground simply because of his broken and versatile kit

Now for the actual question. Do yall think maokai is Overtuned or broken?

In my personal opinion he's just overtuned right now along with the combination of tank items (heartsteel sunfire thornmail and twinguard) being really good too.
