[Question] Are there new PvP games?

After doing a search, I found that Nightfall offers 2 new PvP maps, a couple of GvG maps, and the Hero battle. Are there any other new styles of PvP in Nightfall? Kind of like how factions offers AB and Aspenwood.

Just wanted to see if it's justifiable to buy the PvP edition instead of the regular version for a PvP-only player.

Thanks

how does 1 gain access to hero battles
