A couple questions

[bluzer]

1) How many Ethereal crystals do WB's drop? I have seen people claiming WB's drop plenty of ethereal but I have been averaging 3 per kill
2) Is it realistic to think anyone is gonna farm over 10K for gear at forges at that rate? (10,000/3=3,334 kills) or do they?
3) Is there anywhere else to farm ethereal crystals? don't mention WB's in heaven or hell - PK enforced and already lost crystals there - i think it is stupid (just being kind) to force PK on those who don't want to PK
4) Is there anywhere starlight crystals can be exchanged for ethereal?

ok it is more than a couple!

Fixed armors aren't realistic in general unless you have an ABSURD lack of life to farm them. 

I suggest giving up on those, and if you want to farm. Farming for EC instead.

3: Heaven/Hell world bosses. If you can SOLO the Primal weekly, do so.
4: No.

Regular world bosses are straight up not worth farming. You don't like that answer, well, tough nuts.
