Really love Maokai but i've never dared play him in a ranked match because i've never seen him (EVER). Any gold rated(+) players here play him or think he's a viable?

yes

I've played maokai jungle in ranked. Works great if you know how to play him
Ranked match I've played with him I got 4/0/5

if you're good playing as maokai, go for it. nobody stops you

Apparentley maokai jungle is viable and pretty good at that. I never really see him so don't know completely.

Better options if you need a full tank build, but with high AP burst build he can be very effective solo top.

Nice!!! Christmas Maokai skin here I come :P

maokai jungle is kinda broken op to be hones who knows soon new fotom.

In the jungle his viability is unquestioned. Top/Mid you have to watch out for counters. I have heard of Mao support but I can't really comment on that.

Watch Oddone stream.
