No, adding in extra keeps, updating towns, updating IC, and updating BGs do not count. PvP has not had a legitimate DLC since Imperial City which was over 3 years ago.
I suggest adding in either 3v3/4v4/5v5 Arenas (this is a common PvP feature in nearly ever MMO) or adding in a free for all open world PvP zone (also a common feature in many MMOs) where only your grouped members would be unattackable. I dont know the Lore but I’m sure someone who does would know of an adequate zone this could occur in at this time period? Would appreciate it if you could give that input.
