What's Maokai's weakness?
I've been playing Maokai recently because I liked his CC and peeling potential as well as amazing in-combat sustain, and I won lane against both Renekton and Garen, who are known for being amazing laners. I'm still low elo (or MMR since I'm not ranked yet), so maybe people don't know how to play against Maokai, but I'd like to learn some weaknesses of Maokai so I can be a better player.
4*
against anyone who scales off AD (sometimes even 3 hp and 2 mp).
I think you're right in that he has no good poke, since his E is pretty easy to dodge. I used it against Garen to prevent him from procing his passive, but otherwise the damage itself was meh.
&
core?
