The blue can win easily on Blitzkrieg map?

Don’t you think in this map blue it’s more easy?

Yes, we recognize the unbalance issue.

Though we have changed the locations of blue/red flags several times, we still haven’t found the best locations.

Why the blue team can win easily – possible reasons:

  • The position of the blue base is higher than the position of the red base geographically. (advantage for offensive)
  • The blue flag stands on a flat ground, while the red flag stands on an uneven ground. (advantage for defensive)
  • The blue players can camp at a house near their flag. (advantage for defensive)

Please give us your advice if you have any ideas. However, we can only move the flags, and we cannot modify any structures such as wall or ground.
