a few questions on Ursaan doa farm

I have to premit i never ever entered doa.
recently i got max lb and a decent rank in norn allegiance, so i thoung i might try a few runs in "easy-mode-way"
so..here we go:
1)which build i'm supposed to load , apart from the elite? I'm a ranger (in other areas i usually go /para wiith echoes or /mes with mimicry ) and i have all the campaigns.
2)is it still a decent area to farm? or i'm better off farming the 35ectos for the armbrace in uw? (like i'm doing now)
3)how much time i actually need in an average ursaan pug team to complete the 4 zones and kill mallyx?
4)how harder in HM? timewise, to get more gems, HM or NM?

thanks all

1.) Except UB I'd say para with echoes is fine,asuran summon skill,vanguard sin support+ress in case you get whiped (rebirth (+) sunspear signet).

2.)Yes,it's still decent area to farm. Not much profit but as it used to be but atleast it's steady income,meaning,you'll get atleast 10 gems (in NM that is) unlike UW where it mostly depends on luck.

3.)Average pug team with let's say.. r7+ Norn takes about 2-2.5h(less deaths and stopping,the better ) to clear 4 areas,and Mallyx takes no more then 20 minutes.

4.) HM is well... harder .There are though areas like for example hungers in Veil,where they'll most likely touch few ursans to death unless monking is good. And if you're doing it with guild/alliance/friends/whatever where everyone knows what they're doing run shouldn't take more then 3-3.5h where it's better than NM PUG. But if you wanna PUG HM,don't.

Hope that helped. ^^
