Glaive/Bow is the best IMO. Get mobs to gather around you with the bow skills like this:
4 multi-arrow one mob
3 multi-arrow another one
2 multi-arrow a third one
and so on, until you have like 6-7 mobs around you.
Then, switch to glaive and use ghost spear skills. Pretty much like this:

It's just, that the luring of the mobs is done with bow skills rather then nukes/cold waves/flying dragons.
Glaive/Bow builds are great unique hunters because they can stay away and shoot bow skills from a far, rather then take all the damage from low range.
In PvP, they also do well. You should play like this:
Fire/Ice Wall -> Anti-Devil -> Berzerker Arrow, switch to glaive, Soul Spear -> Ghost spear etc.
You can also ghost walk away and repeat the cicle. It has the advantages of awsome crits and stuns/knockbacks
Overall, the build is great both in PvE and PvP.
But keep in mind, that the 90 cap and the new skills will come. This will make any dual weapon build very ineffective, because of the mastery limit.
