A
1. Decrease Militia Length
2. Edit maps if necessary so that creep camps are not too close to spawn location, keeping in mind distance between spawn locations.

B
1. Add un-buildable terrain immediately around creep camps, or change creep camps’ aggro radius
2. Change creep camp AI so that creeps will move back to their camp location after they move out a shorter distance than it is right now.

A nerfs human creeping. B nerfs elf creeping. Both only slightly though IMO

Balance problems are really cause of MAPS I think. Tournaments just need better map systems (and better maps!)
