FIX JUNGLE
So now, with the new jungle changes, if you forget smite you're out of the game. There's no chance of getting back in, it's a 4v5 from then on. I played with an Evelynn and she couldn't solo a camp at lvl 7. Frankly, I think this is unacceptable. You shouldn't automatically lose the game just because your jungler forgot smite (which is a VERY easy thing to do).
I guess if you wanted to circumvent this very aggravating situation, Riot could add an option to either 1. change summoners in the first 1.5 minutes or 2. enable a surrender vote for the first 3 minutes. It's really not fun for the whole team when this happens, and it needs to be fixed. Duoing a lane isn't viable anymore; not only are you letting the other jungler take all of your camps, you're also splitting xp and putting your top lane behind.
There needs to be something in place to prevent this; top lane typically doesn't lose the game because they didn't take tp, same with mid and ignite; they might be put a bit behind, but they don't convert the game into a 4v5.
