I have some mixed emotions about the pillars and grass in Midlane.
On one hand, I think they are great for defensive plays. To disengage and create space.
But for characters like Wraith and Neon with a built in invisibility, it can also be oppressive on engagements. Using the pillars to break line of sight and invisibility to slide into the grass unseen. Even if you ward, Neon and Wraith also benefit from added mobility when they are invisible to engage quickly.
As a Wraith main, I found it very easy to navigate and weave in and out of the pillars to poke and harass my opponent. And the thought crossed my mind as to where it was an NPE.
Maybe if the pillar or grass were set out a little wider, it could at least give people a way to space themselves from characters with that built in invisibility.
