How this will benefit the site and/or other comments:
- Change the XML of older maps to ensure fair drops
Specifics/Details:
- Many drops start with players having territory count that is a multiple of 3, therefore potentially owning a larger bonus than the other team. As per oaktown's Gameplay suggestions in the foundry, located at viewtopic.php?f=466&t=81664#p1921330 (in the Balanced Gameplay/What to Avoid section) this is an unfair advantage
- Even though a map has been through the foundry process, it may not be fair, especially if the requirements of the foundry change
- As long as the original graphics are unchanged, there is no issue with the copyright given to the site as per the copyright agreement
How this will benefit the site and/or other comments:
- Make maps fairer for all game types
