Here what I will do if Im in your place.
Main weapon,
I would use frozen fate or munity. I donāt think I would use sword throw that much, beside it just used once in a while so the +100%WD (which is boost that weapon ONLY) arenāt important, I would use +100%ED instead for support OH damage.
Off Hand Weapon
I would remove that legend affix +%Movement Speed and replace with +5000WD, that your primary damage dealer tho. It would be better to do so, beside smokebomb can take that advantage to gain more damage when it proc.
Armor
U made fatal mistake on this part by choosing brutal over reptured. For BLEED build reptured always better. Brutal effect on deadly strike, its chance by chance (Chance for crit> Chance to deadly strike). While reptured boost damage just by applying bleed, since ur mainly toss bleed build apply bleed arenāt difficult. The result also better.
Here some example on dealing 100m damage with 200%Crit damage :
Brutal
100m*2(crit damage) =300m (900m damage when deadly strike happen)
Reptured (on bleeding enemy)
100m+50% (reptured effect) = 150m
150m*2 (crit damage) = 450m (900m damage when deadly strike happen)
When u look at it spike damage (deadly strike, they deal the same but the reason why I said reptured are better for bleed build because the effect (damage boost) last longer, as long as enemy bleed, you can deal more damage in that 10sec (bleed duration) while brutal only when deal deadly strike.
Helm
Honestly what the reason u use resource mythic equivalent? It boost nothing in your build. U have different HP/MP pool due to glasscannon, u will not gain any benefit beside wasting 1 slot. Make new helm using masochism item, get that 50% Barbarian make desperation mythic.for ur +50% glasscannon on helm, u can just remove push over limit on ring.
Currently your 100%Glasscannon+100%Push over limit
((1*1) *1) = 4#
With my suggestion 100%Glasscannon+50%Push over limit+50%Barbarian.
(((1*1) *0.5) *0.5) = 4.5#
Even the boost seem small its bigger in damage thoā¦ The layer, damage multiplier is monster, keep your eyes on it.
Ring
Like I said above, just remove that push over limit and get the glasscannon back. For the talent depend on u, zealous for more damage or u can change to suffering, at rank 30 if I remember correctly its 75% bleeding enemy to miss.
Necklace
Congratulation.! the only part I donāt see any trouble. Lol
For heroic,
19 (Sword throw) since u not able to use constantly.
20 (Toss) ur primary lol
20 (Dexterity) get the tiny bit more ms dodge and CD.
20 (Intelligent) seriously I donāt get it why u add on strength lol, its not like u can boost HP, beside having 10k armor while having 1HP will not give u anything, with intelligent at rank 20 u gain more mp and more important is that +500Pm regen, u have +500mp regen in pet, so it will be good to boost regen for desperation.
500+500= 1000*1.25 (Cosmic power mp regen boost) = 2250MP regen. Good enough for unlimited toss spam.
Look at ur hatcher, toss cost 1040MP, but since it have 50% push over limit, the cosy will be 1520mp ur mp heal with desperation is higher. So it safe to said its spamable.
For hero point
U will have 60k+ without equivalent mythic,
So I suggest u to respect and just add little bit in many if the total is less than 10k. If it already more than 10kMP, the rest point u can put in Power for more damage.
Lastly I donāt think this build need resource mythic since to begin with your equivalent mythic doesnāt increase any damage to begin with. So it safe to say without that equivalent mythic its not effect ur overall damage.
Now bow to the king, (Lol Just kidding)
Edit: I saw u have +300% remove one and add +15% m.speed coz in my suggestion I ask u to remove m.speed on your OH weapon, core boost important tho lol
