One account can only earn a total of 6,000 faction per day from the Zaishen Elite. Faction earned in Zaishen Challenge or Training Arena counts against this limit. After earning 2,000 faction in Zaishen Challenge, Training Arena or Zaishen Elite you will not gain faction from kills the first 2 rounds. The third round can be farmed up to 3,000 faction, fourth round up to 4000 faction, fifth round up to 5000 faction. You can still earn faction from Guild versus Guild, Random Arenas, Team Arenas, Hero Battles, Alliance Battle and Heroes' Ascent after getting 6,000 faction in Zaishen Elite.
so i found out that you can get Balthazar Faction from farming the Zaishen Elites. and i want to share my trapper build with you. its pretty easy to use. anyone can do it if they have all the 3 rangers heros, if you don't you can always use other heros and give them the trappings skills, but its slightly harder then if you were to use the ranger heros.
Off course you can change the skills around. However the trick is where to lay the traps, this I won't tell you, this I'll tell you, use corner to your advantage. At least do that part yourself.

this are the skills sets
build 1
[build=OgATYxLj1R5scaO7ynzw13IAAA]
build 2
[build=OgATYxLj1R5scaO7yhL0x3IAAA]
build 3
[build=OgATYxLj1R5scaO7yh71x3IAAA]
build 4
[build=OgATY17i1R5scaOFHg7us7IAAA]
see easy but, heros sometimes don't lay traps unless you tell them. but they do lay down the spirits, so, don't let them cast the spirits upon entering the battle, because this will destroy your plan, sometimes the zaishen elite will run towards the spirits instead of running towards you where the traps are.
Yes, forgot about the weapons 40/40 wands and off hands

Notes:
1) somehow, i've not found out what they do yet, but the zaishen elementalist manage to take out the frozen soil pretty easy and fast.
2) and if you meet zaishen group thats both caster and melee, watch out, cos the melee will be dead sometime leaving the caster at a safe distance from the traps.
have fun

I did search but did not see anyone doing this so.
