I think Maokai should have had some of his reliability reworked in the tank rework
He's the poster boy of the "brainless" tank as most of his CC is point and click and on a low cool down. And while W certainly is one of the easiest forms of CC to apply I think his Q, Bramble smash, should have been reworked too.
In its current form it just does too much: -It deals a lot of damage on a medium-low cd -it has cc attached to it -it has not a lot of skill expression
Honestly, I thought tank damage was supposed to become less reliable so why did Maokai keep most of his unintuitive damage patterns and too reliable cc abilities while also adding a huge AoE root to his kit?
