What is the reason why Summoners Rift isn't a 4v4 map?
I am really curious why the game is 5v5 instead of 4v4, I can think if 1,743 reasons why it should be 4v4 or would function better as a 4v4 map and I can't think of a single legitimate reason why it is 5v5.
And I have been in enough matches where 1 has DC'd from both sides and match quality improves dramatically, so my 1,743 reasons have all been actually vetted and verified as well (as well as winning the vast majority of any 4v5 I get into, and the exceptions are all highly specific set of circumstances required).
I tried looking for riot explanations since they seem keen on intent/motivation transparency but...there is nothing here.
