Stuck on Factions(Luxon/Kurzick)

Well hopefully u all know that we need to gain 10000 Luxon or Kurzick faction to get furthur on in the game, but the problem is that i am stuck on 7880 luxon factions, but i finished all quest that are possible , and the only way to get more factions is to fight the competitive mission in the jade quarry, but there is NOBODY there. the max i saw there was like 7 of them and some afkers. soo please suggest me some ways to get some faction and not stuck here in this place.
Thanks

12vs12..haven't found it yet :/

i tried to get my guildies and i tried to call in calavon for more people to join the but alli got....was rejections... its kinda dissapointing...but faction really dissapoint me...

dont need guildie for your 12vs 12... Just go there, form a party of 4 and win!....

I've gained 789faction in 1 shot for a win!

Or do the Zos Shivros challenge mission with hench, might be real slow but you get faction.

I know in the Kurzak area you can do the mission where you run around and gather amber chunks. If you just grind it with henchies you will eventually gather it all up. I'd rather do that then wait to do the quests for factions till AFTER they fix the ability to buy amber from the Factions Rewards person.

Course, if you want 15K Canthan armor, you can just finish/beat the storyline.
