Wings of entropy build, need suggestion.

Since i'm a straight guy and blondie got some boobs, I always choose Scion as my character since she's avaiable :D.
Lately i've got an unique items i find interesting. Not only does it look cool, but also the potential i can see in it is pretty promising.
Here is it:

This unique is really "unique". So far it can benefit from axe, dual wield and two-handed weapon passive in the skill tree. That means u can save urself from lots of +10 points on the way. Most important thing: It can block as a dual wield - while being a 6L item itself. The price on this piece as i check in market is not too expensive too, about 2.5 - 3ex u can have a 5L with useable roll. If u're not too picky u can easily pick one lowbie sockets to use with about 30chaos orb or even less with some luck.
Anyway, I dont think my current build is at its best, it can still be improved a lot, so i creat this topic, sharing what i'm doing and hopefully get some great suggestion from experienced guys here.
My current items:

Currently i'm level 63
- My main AOE skill is now Spectral throw (faster attk, faster projectile, add fire dmg, lmp 5L, will add life leech if 6L), 1k6 dps with hatred on (all gems are non-quality).
- Main single target is Dual strike (multistrike, faster attack, melee physical damage) at 11k dps - 4L. I'll add life leech and add fire damage if i have 5 and 6 links respectively.
- Aura: currently running hatred and clarity (i keep clarity at level 9 to balance the mana reserved with the regen i actually need to run my skills without mana flask).
- Support skills includeding: Leap slam for movement,Summon skeleton with spell totem, minion life and blind (4L) as distraction and support tanking (pretty good at tanking projectiles - both arrows and spells).

Skill tree : I'm currently farming dock merciless, pretty much i do all stuffs solo because my connection is kinda poor to handle a party farming. At level 63 with quests, i have 77 skill points

Skill tree i'm aiming for:


About gears, Wings of entropy is essential of course. For other items i just try to pick up as tanky items as i can, with life, resist. For boots it's better to have movespeed, it does help a lot in all cases. you dont really need dps on gears, since u got a lot from passive. Wings of Entropy as i said can benefit from all Axe, 2h and dual wield passive, lots of 24-32% dmg nodes.

Currently i dont have too much time to play, so just sometime i'm on the game i only farm exp and get some maps from doc if possible. Idk if this build would be viable for maps or not. with flask effects i have maximum 16k armor with my current gear, life is about 3k3. Farm docks with fast projectile spectral throw is really fast and easy, since the range u can cover is huge.

My concern now is: Is spectral throw the best choice at this point, sometimes i feel like dual strike with splash as AOE might do more dps. Plus should i use Bringer of Rain with dual strike.
Also i'm thinking of changing my support skills to decoy totem + cast on dmg taken, seems to be a better distraction.
About dps, i'm wondering if i should use hatred or wraith as dmg aura, since hatred scale from ur physical dmg, which means lots of potential, also the chill and freeze effect is good. But on the other side shocks seems nice too, since the 20% shocks is only one 10pts int away from u (close to the hp+chaos res).

Please if you read to this point, give me some comments and suggestions. So far i havent die on my solo run, just some trouble with dominus, i have to move back to town when he do the "bloody rain" trick :| idk what kind of dmg that is, cant survive it without going back to town and back up :))
