ive been working on this. i think i got it figured out. so you max throw mastery. then you are free to do anything you want. there are 2 ways to make this build. warshrike version and everything else.
they are defiantly viable in p1.

everything else gear: offhand beast and done. almost you will need some ias gear if you have a big damage ghost glave.

warshrike: you need enough skill point to to throw mastery to get 50% pierce warshrikes have 50%. you can't get there with torch anni and 20 base. use highlords and gores so you will have 100% deadly strike. then you will use a phoenix monarch for the offhand.

What weapons do you have on your other set of weapons? (battle cry weapons to buff your health / mana?)

You may of not considered this, but why not just equip dual melee weapons (or weapon/shield if that is what you prefer) and dual throwing weapons just like a hybrid amazon?
Using double throw is much better than 1-handed throw.

yeah this is meant to be a hybrid. i made to be a ww hybrid but it could work with almost any barb build. it's hard to find the right balance between throw and ww. also i only have 1 eth warshrike. i was using lacerators and double throw but i like this better.

Phoenix is a Nice offhand wep. Beast is 186% ed, ar and eias, meanwhile phoenix is 400% ed, abs and life.

yeah it works way better than beast for the warshrikes. they are fast enough they don't get ias from fan.

But, you may want to check out the higher damage javs.
Razor = 30% pierce or smt.

Because:
In d2lod barb got multiplicative ed from throwing mastery if single throw. And that will benefit more on a higher damage wep. Might need to use beast then. And dno if patced in d2r

i have is 400 damage ghost glaive it's still kinda slow but hits hard. ill try it thanks

a dream monarch actually works with the warshrike set up too. that makes me wonder about a throwing auradin. also i found a wisp tonight. ive been using it idk if it helps any but would be good on a throw sorc.
