Elemental Arrow this is your hatred generator/damage buffer.
Cluster Arrow is your nuke
Preparation is hatred filler/whatever rune you like to take.
Companion is minor damage dealer and major damage cooldown to use with elites
Marked for death is damage buff + cleave
Shadow Power/Smoke Screen is the defensive cooldown.
Passives are self explanatory i think just more damage and discipline regen from crits
Cull the Weak (Frost arrow snare)
Spamming FA to single trash to kill them and FA+CA to groups
Elites > mark them with MfD > Use Companion buff > FA/CA/FA/CA depending of your attackspeed or FA/CA/CA/FA and repeat when you run low of hatred use Preparation for more hatred and nuke those Yellows!
Also i tend to use CA fairly often in trash so i can use Preparation to fill hatred so i can actually regen my discipline trough passive.
the damage is massive in my opinion i can farm T3 pretty fast, trash dies on oneshot and you can nuke elites pretty fast and the companion makes a handy tank sometimes.
Some hatred regen pieces make life easier as well discipline pieces, i got 2 Disc pieces + set so im at 55 wich is great but not madantory, since i started without them the playstyle just got smoother after getting the disc parts.
fill the gaps in your gear with the paragon points if u can.
Dex/Hatred (Alternating and testing between these)
AR (mine is super low)
What to aim for:
500-700 AR?? i have no idea, since i havent played my DH that much
I still die time to times when im not careful since i got very low Life on hit and AR
Not sure if the spec can be alive at 70 but as for now im loving it.
getting 2,5 million crits is pretty fun.
If any comments/improvisations/suggestions/questions im willing to answer to my best knowledge :)
