I'm assuming he's more talking about PvPing anywhere not just in a certain location..

But the thing is ingame the battles are only done as training exercises between the 3.. should be 5 or 6 by this point.. grand companies.

That's why they have a specific location for pvp and why the battles tend to be kept in the same locations.. just changing the objectives an goals for earning points.

Fighting in the middle of a map would be akin to battles to the death from rouges and such as happens on the maps.
