My biggest concern with Season 10 changes
Vision.
Maybe its just because I'm a support main... but our current vision mechanics are barely sufficient for the current state of the game. The map is borderline too dark as it is... and in the coming season, you're making it harder. Between the new bushes, the new terrain changes caused by the elemental rift, and the alcoves in the side lanes... vision is going to be at a greater premium than ever. And you're making it impossible to have two vision items(not that it was easy as is)
Please, Riot, throw us a bone. Give us some means to have more vision as a team.
Obviously, few people want to go back to the era where supports did nothing but buy wards and ward the entire map - that's not a healthy state. But there needs to be a balance between 'nobody sees anything' and 'everyone sees everything'... and the CURRENT state of the game is almost too dark, so don't push it further in that direction.

(Or add a counterpart that creates vision.. ah wait.. there was, but we remove those...)
