Maokai Set up (help!)

Hello, I have recently started to try and play the champion Maokai after I discovered I had the Meowkai(?) skin for him. However, after browsing the web I still have a few questions...

1. Skill order. From what I have read most people go Q(knock back/slow), W(Root), E(Sapling). However, Op.gg says that Q, E, W has a higher win-rate, while only being picked about 10% of the time. I am wondering what you guys think is better since the higher win-rate (65%~ from 60%) could just be caused by a small amount of games were the player got lucky or it could be old data. Also, Maokai's E is supposed to be getting a buff next patch, do you think this will make it more desirable to max second? Anyway, if its not clear I am wondering what you guys think is the best skill order.

2. Keystone. I am unsure of the best keystone to take on this guy. Aftershock seems like the best, but most people and builds I have found on mobafire and other sites (Yes, I am one of THOSE people...) seem to take grasp. I get that grasp is better in lane while aftershock is better for team fighting. What I am asking is which is more impactful. Games are pretty short right now so grasp won't get that much use right and Maokai likes to team fight which is making me lean towards Aftershock. Just as a note, I usually go bone plating/font, the healing one, and the one that makes heals better, then as a secondary I take Sorcery and take manaflow band and the one that gives 10% CDR at ten minutes. Anyway, I essentially just want more input about which one is better right now.

3. Lastly, is Jungle Maokai viable or should I just stick to the top lane?

Thanks for any tips you may provide and my apologies if this is in the wrong place!!!
