MAOKAI BUFF

Passive - Really unique, but can be useless when facing someone with a grievous wounds item. What if Maokai gained an increasingly immunity to grievous wounds for each level?
Q - It's fine I guess.
W - Make it either stun, longer in radius, or able to target allies or saplings with.
E - Make Maokai able to throw the saplings onto champions. (Must stick on their face and scream)
R - It's useful but boring. What if Maokai instead stuck his magical fist into the ground, channelling for 1,5s, marking target area for the duration, and then plants would rise from there (Somewhat like Fizz' R) in a radius of around 70% of his current R's length, rooting and silencing enemies whilst pulling them over to Maokai?
As of these new ideas, I think that Maokai would get really OP, but then I'd say that it can just be balanced by damage reduction, less mana, more cooldown, etc.
What do you think? Do you disagree with any of my suggestions? Let me know!
he can snowball well while investing other items for tanking.
Also that insane base attackspeed, holy it's so good for splitpushing.
