Those plants in jg give some champions too much mobility + vision ward is gone.

Some champions can kite very hard like Rumble, Jayce or Jhin and those plants even make jump over the wall like zac or vi. I just think it's not balanced to have those plants there in jg. Also some champs can be invisible and since there is no vision ward we can get camped too easily. For example,shaco, evelynn or rengar will already hit you when you see them. It is just too hard to escape. You just have to give us something that can help us avoid these. I just think last season was a lot more balanced than this season. (I know it's just preseason but last year's preseason looked a lot better than this).
