So few things to note.
Sorted by plat+ here are the recorded statistically significant champions by class.
Adc 17
Top 52
Mid 46
support 28
Jungle. 47
every game has 2 of each class. As you can see ADC has less options. Most the player base is not Plat+ so lets take a look at what the rest looks like.
Bronze Silver Gold Plat
Adc 18 Adc 18 Adc 18 Adc 17
Top 49 Top 51 Top 51 Top 51
Mid 46 Mid 47 Mid 46 Mid 46
Sup 34 Sup 32 Sup 29 Sup 28
Jung 32 Jung 47 Jung 48 Jung 47
See a trend? whaaaat theres less options for ADC but the same expectation to see 2 of them for each team? ge golly gosh would it be unreasonable to expect that class to see its champions have higher pick % because theres less options available to the players?
Numbers don't lie, don't try to make them be misleading please.
I can honestly say the top 5 out of 5 top banned champions are MID lane, clearly mid lanes an issue for players, If mid was NOT SO OP why would they take up the top bans for plat +? shit like this, Its misleading so please don't do it.
