Not really sure how the actual map is going to work, and if you have already come up with a method then forget I wrote this

.
Week 1: 4v4, 3v3, 2v2, and 1v1 maps are chosen as the "battleground" for the weeks engagements.
1v1's = 2 point, 2v2 = 4 points, 3v3 = 6 points, 4v4 = 10 points.
Team with the highest score at the end of the week wins. (lets say AXIS)
Week 2: Depending on who won (AXIS), a new 4v4, 3v3, 2v2, and 1v1 map will be chosen as the new "battlegrounds". At the end of the week, points are totaled, and the ALLIES win.
Week 3: Maps = same as week 1.
So creating a sort of map path to follow after the winner is declared after each week.
Example:
(English Channel)5-4-3-2-1-2-3-4-5(Berlin). Starting at 1.
All maps chosen, for each number, will be related to the terrain of the area of the actual "Map". So if the fighting is taking place in France, only 4v4, 3v3, 2v2, and 1v1 French setting maps can be used.
This way, people could standardize their maps to say. #1 map list (all maps dealing with the #1 slot)
All #1 maps must require .. such.. and use ... this... and contain .. this.
All #2 maps must require.... etc. etc.
Attacking or defendingScenario 1:Axis = 35 points
Allies = 42 points
(4v4) Axis defend against Allies attack
Allies Successful Attack = 100% points (10)
Axis = 35 points
Allies = 52 points
Scenario 2:Axis = 35 points
Allies = 42 points
(4v4) Axis defend against Allies attack
Axis Successful Defense = 20% points(out of 10 possible) & -50% of total points from enemies(50% of 10 possible points).
Axis = 37 points
Allies = 37 points
Maybe this could be worked around a little, but you could give some sort of limited number of attacks and defends. So sides wouldn't be attack hungry, and actually force a side to defend, to save up for a battle of the bulge.
The numbers aren't set it stone, so instead of bashing the math (I realize that getting 20% of a 1v1 would be a decimal number), just offer your own suggestion. What do you think? ideas? comments?
