Who hates the EXP split?

I've notice this that most game I lost was because of the same issue of EXP split. ADC got 1st tower and then comes mid.

I was stomping Cass, but in the end we lost the game cuz I was lv 15 and she was lv 17. We had the same amount of CS but 1 team was grouping and the other team wasn't.

Most of the time she survived my burst is because of her living with the slight amount of HP.

Can we do something about exp split?
