Why do we fight mid at level 1 and how do we abuse it?

Fighting Mid is something we all do without thinking these days so why do we fight mid? Pros fight mid because they want to stay groupped and be in the middle of the map to prevent enemies from cheesing towers or to prevent enemies from hiding and trying to flank. Groupping also allows kills during enemy rotations. Otherwise there are 3 things you should look for in fighting at level one. 1: Do you have quests with high value to complete early. Some quests can get a lot of stacks mid and those stacks can be the difference of the lane. 2: Does your team have an early combo like a hook that can lead to an early kill? 3: Does your team have a weak level one with maybe a varian? Or a strong level one with a tracer? Taking those 3 things into consideration the value of simply soaking lanes is worth more than a couple kills. So If the enemies have more quests, more kill potential and/or a stronger level 1 you may just want to soak instead of fighting mid. Also I talk a bit about The Art of War and Social Cognitive Theory.
