Effects of the lvl disadvantage in the duo lane.
It means you are more vulnerable to the assassins due to your lower hp pools. If you are 2 lvls under the average lvl on the map, then you have about 140 less hp than you would. At lvl 9, thats about 10% less hp and first of all, that makes you much more vulnerable to assassins and as the support and adc, you are the primary target of assassins and assassin fighters. So theres that.
Second. You cant get blue trinket early enough. This is pretty unfair in my opinion. I think if I could grab the blue trink earlier as an adc I could have better games. But im stuck in a duo lane because theres only 3 lanes and 1 jungle, but 5 players.
