There actually is a reason because if you look at the individual skill in between the elos you can see , that the skill difference between D 5 and D 1 is so large its unbelievable . Even the skill difference between a high Challenger and a low Master ! player is really significant . I am Plat 2 myself so i am in the top 3 % of players but i still do not consider myself good at this game in the slightest . I can and i did comfortably smash every opponent below plat 5 when i was boosting my younger brothers account , sitting on a 90 % winrate from b 5 to gold 3 and again i am just Plat 2 . What im trying to say is , that the skill difference in league is huge in between the brackets and youre not to be considered good unless you really are in that top 2 %.
