Nothing is going to change with laning if the JG doesn't get nerfed as well

In particular the JG's early game will have to be nerfed along side these minion changes.

Mid laners aren't just shoving in so they can roam. Shoving the wave in also makes it more difficult to get ganked when you can chill near tower with your spells up and ready.

Sure I can stay near the wave and contest the CS the enemy laner is trying to get but if the enemy JG shows up then I'm probably dead or at least blowing flash. The times I can try and scrape it out with the other laner are so few (if ever) because I need to know where the enemy JG is and that they aren't near my lane.

So why risk dying for a potential CS lead over the other laner when I can just back or try to roam?
