What is the logical game winning REASON for 2 bot ALWAYS
Every game I noticed there are 2 bot, 1 mid, 1 top and 1 jungler for both teams EVERY SINGLE TIME. I understand 1 mid and 1 jungler every single time.
But why can't we do carry+support vs tank(or whoever solo lane that is not mid). What is so special about the bot lane that demands 2 people always go there.
And why is 2v1 top and bot a big no no or why 2v2 top is not allowed
