Mostly a quick readjustment of the rollouts this edition.
Only major change to Mid was splitting the single staircase into two, for better flow on the lower area of the map.
No more Door into rollout, as I felt this was causing people to be a bit too cautious heading in there, and thus encouraging the other team to head into it and spawn camp a defensive team.
Note the addition of a extra route into the side flank, for sneakier flanking if you do happen to get spawn camped.
It leads to a dropdown, allowing you to flank around.
