an Alliance battle suggestion

what if we make the line shift directions no mater who is winning? i mean, we have only fought so far in three maps before the edge of extinction and saccers got in:

Etnaran Keys (Shallow Luxon)
Saltspray Beach (Neutral)
Grenz Frontier (Shallow Kurzick)

we could make the line go from luxon deep territory to kurzick deep territory no matter who is winning.
Kaanai Canyon (Deep Luxon) ->Etnaran Keys (Shallow Luxon)-> Saltspray Beach (Neutral) ->Grenz Frontier (Shallow Kurzick) ->Ancestral Lands (Deep Kurzick)

every three hours the line gets updated, why not make it always change, so that we can fight on other maps:
three hours pass, the battle goes from saltspray to grenz frontier, three hours later no matter if the kurzick wins or not, the line moves to ancestral lands, three hours later it goes back to grenz frontier, three hours later it goes to saltspray, three hours later to etnaran keys, three hours later to kaanai canyon.

It's all about territory, you can't just change it because you want to play other maps more often...I mean, I get tired of Etnaran and Saltspray all the time, but changing it would just ruin the whole idea of the alliance battles.

this would ruin the drive for either side to gain power, and you forget, the two deep-territory maps allow the other side to have more towns under their control.

well then, what about allowing the map rotation and let the line move according to the current algorythm?

Well the maps are supposed to represent the desperation of each group. For Kaanai Canyon, for example, the Luxons are on the verge of defeat as they've been pushed back so far. Thus, they contain themselves in their impregnable fortress and attempt to oust the Kurzicks so they have a fighting chance again.

So map rotation becoming independent of the line would create lore inconsistency, which is a problem Anet generally likes to avoid.
