What?
Really?
2000 players per map, 6000 players per server.
All Alliances fight at the same time.
The game never ends, it's an eternal war.
You need quite a computer to run it, the HW requirements are too high for me for example.
I have i5 cpu, 7950 gpu, 8GB ram and its ok
Last time I heard that never happens because most servers are underpopulated for whatever reason.
I play it from the beginning , i play on EU server Cobalt. And at night its like 3+ battles with 45+ players per map (and of course a lot of small fights 12v12) but map is realy big and server have 3 different maps. When a large clans join its like 200v200 or more

.
But when the count all players on the map, it is enough.
