How does the AB map rotation work?

I thought it was based on win/loss ratio. But now almost everybody wants to play on the Kurzick side because the advantage is so huge, and you only get 1k less Imperial faction for winning, and the map (Ancestral Lands) still won't change.

from what i recall when i did ab - every 3 hrs depending on overall total of win/lose the map either shifted towards kurz or to lux or neutral lands (forget name ).
And the overall is across all language dists .
So if ur saying everyones shifted to kurz - how comes theres matches being played as you imply theres no luxons playing :S.
If stuck on ancestral lands then it simply means kurz are seriously losing and lux are winning most matches .

For some unexplainable reason, Kurzicks are usually absolutely horrible at AB. No idea why or how, but it's just a fact..

Now, indeed, the map changes based on a 3h basis (the same time the towns get updated) based on who wins/loses more. So if you lose a lot, you get an advantage by being on your own map, hopefully granting you more chances of winning...

Alright. It would be nice to actually be able to see the statistics. It's very hard to believe Luxons won more games than Kurzicks yesterday.
