Looks like a nice beginning! Haven't tried all scaling health runes. How healthy is your early clear with that?

I'd suggest Turbo Chemtank as a solid buy if your team needs a good method for engaging and Twisted Advance isn't getting the job done. Maokai is amazing at locking down one target and then disrupting the rest of a team fight with his ultimate.

I suggest having a section on how to use his saplings to clear the jungle as the micromanagement of that is peculiar to Maokai.

Also a section on how to best use his ultimate.

As I alluded to above I find the most success when I used Twisted Advance to get into the middle of their team and then cast my ult to try and catch as many people in it as possible so that their escape is impeded and they can't come to the rescue of their initial target. But I'm definitely on the lookout for other effective ways to use it, because there are definitely wrong ways to use it since it moves so slowly.

for some reason rune page didnt show - just use all scaling health runes and quintessences
