No they aren't ' Everybody zergs are 1 point is pure bull****'
Its guilds that can muster up 25 ppl at the most and guilds that can muster up 50 people or close to it.
If we pvp and we start with 10 vs 10 and half of the members leaves leaving it at 10 vs 5 its not a zerg.
And pvping 13 vs 10 is not that big of a deal either.
