Basically i do not understand how AB works in deciding what maps are going to come after a certain amount of time... I have been told that every 3 hours the map changes after looking on wiki i have not seen any information on how the maps are decided is it down to the amount of faction accumulated in those 3 hours so if the kurzicks gain 20k faction and the luxons gain 15k would the map move deeper into the luxon maps for 3 hours. Or is it down to the amount of ABs won For example Luxons on Ethren keys win 34 battles and kurzicks win 23 would the maps move into the kurzick maps? or is it random?

because after doing a large amount of AB recently i can honestly say it is on the luxon maps more.

Kurzicks have a large faction income from HFFF so if the faction determines which side 'wins' kurzicks should pretty much win all of the time that would explain why it 'seems' to be in the Luxon areas for the majority of the time. I wonder if anyone else has noticed this.

I would like to finish by saying that i am not claiming that a side is better than another side. So i dnt want any posts saying im QQing

-Yes

It's like Tug of War in WiC (lawls). You have 5 points (aka frontlines);
K-K-O-L-L

O = Saltspray Beach
L = Luxon territory
K = Kurzick territory

So if you win 34 battles in Saltspray as a luxon, versus the kurzicks 23, you'll move into the first kurzick zone, where they will have some advantage - closer to points and such, and vice versa.

The movement of the border as seen on the map of the continent is the primary effect determined by wins during the latest three hour period as well as wins during the previous period(s) (known as 'momentum'). The actual AB map is chosen based on the border and not the other way round (there are three different border positions corresponding to both shallow and deep maps, but only one corresponding to the neutral map).

The actual implementation is not known - it may be based on simple difference between wins and losses, or the total amount of faction gained by each side in the matches. Donated faction is not used, so your concern about Kurzick HFFF affecting the outcome is unfounded - only AB matches count.

To understand how the momentum works we assume the simplest possible algorithm. Let's say that integers from -6 to +6 correspond to different border positions, zero being neutral ground and the extremes corresponding to deepest penetrations into Kurzick and Luxon territory, respectively. The current position is a float which is rounded to nearest integer to obtain the respective border position. For each three hour period the number of AB matches as well as wins on each side is counted. At the update, the following formulas are used:

CurrentChange = (KurzickWins - LuxonWins) / GamesPlayed + PreviousChange
PreviousChange = CurrentChange
CurrentPosition = PreviousPosition + CurrentChange
PreviousPosition = CurrentPosition

Now, let's assume that we start from a clear slate on the neutral map (PreviousChange = PreviousPosition = 0) and out of 120 matches played Kurzicks win 80 and Luxons 40. We get

CurrentChange = (80 - 40) / 120 + 0 = 0.33
CurrentPosition = 0 + 0.33 = 0.33

Kurzicks have gained some momentum but still not enough to get the map changed. Let's assume that they win the next period the same way (80 out of 120). At the next update the values will become

CurrentChange = (80 - 40) / 120 + 0.33 = 0.67
CurrentPosition = 0.33 + 0.67 = 1.0

The map now changes to shallow Luxon. Let's assume that because of their advantage Luxons take the next period with 80 wins out of 120. The values will be

CurrentChange = (40 - 80) / 120 + 0.67 = 0.33
CurrentPosition = 1 + 0.33 = 1.33

This shows that the border is still shifting into the Luxon territory despite Luxon wins in the latest period, because of the momentum gained by Kurzick wins in the previous periods.

The momentum acts as a positive feedback mechanism, making the border swing from one extreme to another and back instead of quasi-stabilizing into some particular position. This is a conscious design element since blitzkrieg is more fun than trench warfare.

Wha? you used numbers to explain your point Aaaarga i dunt wanna read no more its the weekend.

Maybe you should put that into simpler terms, not everyone here is educated, me included.
