Riot Please change the Current exp system, and items

In the new patch, AD and Support share one lane, but the shared-experience decreases 5% total, and solo-experience increases. In a game, Mid and Top usually have 3 to 4 levels ahead of ADC and support. Especially when AD encounters mid assassins, support can do nothing for ADC. Because of 3 levels ahead, assassin kills AD so easily. Also, the new items changes, lethal items are more than before, it is so unfair for ADC. On the other hand, AD items change a lot, Zeal increases its value, and it becomes more difficult to make, and the property of the item doesn't buff a lot.
