Its an interesting idea in that it breaks up the geography of the current map. But what is to stop a clan from simply spreading across the trade zones, or caping 2 villages that sit on the border of the zone and send huge shipments a short distance for that 150% bonus?
I suppose you could create an uneven demarcation line so that it twists and turns around clumps of villages to get rid of the second problem. The clans caping a line through the trade barriers though, that's another thing.
The end of the day, people get cheesed by the big alliances by big clans but there was a lot of fighting in EU at the start and these guys emerged on top pretty early on. After that it was just a little bit of a punch up in NA with a predictable out come... being flattened by the monster in the south, and I don't just mean DRZ, the greys or the empire could have done it. The more I think about it the more I think that the end game for this strat was obvious about 3 months back when DRZ took all the cities and castles in its territory and got that 10mill. Its a biased position though, anything could have happened to disrupt DRZ's power and completely change the face of the map, but it didn't the only thing that happened was the Greys got into the same position as DRZ.
I guess now is a perfect time for the Greys to stab DRZ in the back... So is this strat over? I guess battle attendance will be the marker for that.
