Yeah I got your point.
But take as this, there will be only 2 teams. Example if 250 members join the game each team will have 125 members.
125 is not a small amount for a single team.
Both teams place on the extreme opposite sides. It will take time for each of them to travel one place to another covering the area. Once they are face to face 250 players will fight each other. It will hundreds of ticks for a single team to win. Then the winning team will have to go all the way to end to conq them.
For fun we can also place garrisons so that each team will have alot of xtals.
Just like Faction era it could be 3 ticker with 1000 ticks.
PS: admins could decide regarding relics.
