In xi A nation or beast tribe were able to dominate an area. Why not make imperials attack the cities. they are already attacking outside of gridania. whenever a nation looses ground to imperials they should get closer, and eventually reach the city.
once they reach the city an all out war happens for dominance of the city. PvE TIME!!
Catapults, battering rams, rain of arrows, moats. drawbridges. Each would have a significance during the battle. IF we lose the battle they occupy the city until the next Cycle. A sort of "upkeep" would be instilled.
THE GOAL: would be to PREVENT/fend off imperials from entering and reaching a cetain spot within the city. with the use of rams, ladders, catapaults ECT. Not some lame random spawn and stand around
:moved from mechanics cuz nobody looks in there:
