Catch-up Experience

Not much to say on the topic other than the system makes significant errors be met with minor punishment and in some cases rewarded by the sheer amount of xp they'll be gaining off of catch up xp and then killing the enemy laner that was 2-3 levels above them cause they are garbage from 1 jungle gank. All of a sudden they are a level AHEAD of you and their jungler is snowballed because you died once after kkilling them 3 times. How do they deserve the lead I ask as I pull up the scoreboard and see that he is down 20 cs and has more deaths and less kill participation as me? I have absolutely no idea. What allows him to be ahead though is catch up experience which in some cases, as just mentioned, literally rewards people for being garbage and getting one gank from their jungler. Utterly unfair and shouldn't even be in the game, but at the very least it would be great to see it toned down a bit.
