PvP Equipment Question

My friend bought Factions, and on his PvP char, he could equip his Ranger with Canthan armor. On the other hand, I have Nightfall and I cannot equip any of my characters with standard (Elonian / Sunspear) armor.

I'm a bit confused

EDIT: We both have Prophecies.

I don't think there IS Nightfall PVP armour.

There isn't. Never know, when EoTN releases, maybe Anet might make Nightfall skins for pvp. Or somewhere down the road.

Darn it D: Thanks for your replies anyway.
