back prior to season 6 we had what was known as "pick order' you all randomly got put in champ selection... the 1st pick got to ban all 3 bans... and each side took turns picking as we do now... there was no role selection prior to accepting game as their is now.. and based on what order you were put in in champ select is how you got preference of role... say if you were 1st pick you got to chose what ever role and champ you wanted... 2nd pick gets to pick from whats left... 3rd and so on...
now when it got down to where the one side picks 4 and 5 they had to be civil and let one pick before the other or talk and ask what role the preferred out of whats left and on the side where last pick picked by himself got forced to fill whatever role was left for him
this is how it worked for all seasons prior to season 6... meaning being forced to fill was still a thing and every one had to do it... and back then you were expected to be able to play at least one champ in each role...
90% of the time the last pick was forced to be a support. and this before trinkets and sighstone so actually had to use your slots for actual wards and they cost gold, 75gold for green and 100 maybe 125 for pink wards ? i cant remember the cost exactly.
so this was the system most of people honored and lived by... there were trolls and it created toxicity.
but based on this system what roles do you think got picked 1st most of the time? yes thats right MID and TOP so most were forced to jungle before jungle was cool or support.
autofill will not go anywhere... learn to accept it... learn to play more then one role and one champ and all of league and the player base will be better for it...
