I love using weapon throw. is more reliable than WW because fury generation is better then WW. get The Three Hundredth Spear and Butcher Sickle. can up to 200k crit mine.

bro ur DPS was so well but u throw weapon really heavy ,means ur IAS low

how about ur HP regeneration LS 2.8% LoH 443 not really gd enough

how about AR below 300? armor low ,u hard survive bro.....in inferno 1.0.4 i think so so only if talk about 1.0.5 patch u need defensive build alot...

Honestly in AH now u wan find ring skull grasp reduce Fury 4 just have 2 unit only one is 350m,another is 150m.. if u wan reduce fury by 2,price 7m -20m... still have few in AH now.... depends plyer only....

Give us link to your profile.

Do you have enough LOH/LS?
You still can throw axe when you're jailed, right? That should give you life recovery.

Blackthrone too low armor, get IK instead.

My legacy blackthrone set on my DH

Based on your build, you have 400+ LOH & 2.9% LS, I think it is not quite enough.

You only have 244 AR? I think that is too low too.

P/S Try to get another 2%+ LS.

Err... no one can keep the WotB up all the time.

However, we can try to keep WoTB up as long as it can.
The secret is generate fury as many as you can.
1) Use WoTB/Thrive on Chaos
2) Use mighty weapon on your main-hand (it helps in generating more fury).

(Note#1: For me, it is not necessary to use mighty weapon. Axe/Mace are just fine. Anyway, it is no harm to try mighty weapon if you want to)
(Note#2: hit-able is the sifu of mighty weapn. You can check with him on more first-hand information)

Generally you have got a very good build now. Improved AR and very WW build.
You should not have problem to clear A3.
