I definitely think the drones should be worth more. The team that dominates and controls mid should be better rewarded. Maybe every phase, the middle drones are worth a little more than the last, which would function more like a sudden death mechanic for the 6:x and 2:x spawn.

Ultimately I would like if the map's geometry was revised. Rather mid be a bowl, rather than a plateau. Think it would increase the pace in which groups moved if they could use the middle for traversing the map when it's not objective phase, and more flanks would happen.
