Last hitting a minion should grant more EXP than just letting it die next to you
In my opinion, last hitting a minion should grant more EXP than it just dying next to you. Take for example the enemy laner, he has 120 cs at 20 minutes, but you have 160s at 20 minutes, although he has less CS, he is the same level as you, why is that? The risk reward for staying in lane and CSing should be greater, than taking TP, going to another lane, coming back, and having the same EXP as your opponent.
