You can do the pve faction quests. Wars given faction tokens. Just killing people gives up to 200 faction token. I think invasions give faction tokens, but I could be wrong about that.
Myself, I usually play on off hours from when invasions and what not happen, so farming faction tokens for end game pvp gear seems near impossible or a task that will take months of play time and I play a lot. Changing the pvp quests assured that. They are not thinking of everyone they are only thinking of the people that can play the game at the best times of the day. Sad really. Maybe adjust the costs of the gear or something? 50000 takes ages to make. I have been focusing on the pve quests for hours and hours and I have just over 10000 tokens. Seems like its not worth it to do or get those items anymore.
I just ground out my Inquisitor Set on very low pop servers so I hopefully can help you out!
ok so what I did was go to reek water, then I stand in front of the pvp quest giver for about 10 mins or so cycling the quests until I have the best ones for me.
Normallly
I tended to end up with
search war camps for 5 chest 1850
intelegences deliver news 1850
claim terf (stand somewhere for 1 min or something 1500
now then what I did was cycle the top mission until I got three missions that were along the the route id take.
