So I tried out a couple different specs... I went:
#1 - 0 / 31 / 29 DW (mistake! but turned out ok)
#2 - 0 / 32 / 28 2H
#3 - 8 / 0 / 51 - 2H
DPS Results on a lvl65 Target dummy:
Rune rotations were as best I could, consistant.. test times were up to 400K, I used D&D (not glyphed) and HB whenever I could. No trinkets, UH spec used bone shield and I kept HoW up all the time.
#1 - 968 DPS , Spiked @ 1012.2 DPS... simply amazing single target DPS for my level, some of the DPS was splash from AE targets with D&D and HB... but overall simply amazing.
#2 - 736 DPS, Spike @ 815 ... I don't know why I saw this drop. It could have been my rotations ... I felt rune power starved some. IDK. I want to try 2H 44 / 27 spec too.
#3 - 850 DPS, Spike @ 910 DPS.... really great AE, if I would've taken 3/3 Wandering I would have seen even more DPS, but it's all AE DPS.. which is great in certain regards. UB keeps you busy.
I don't really know which one I'm going to go with ... #1 is the highest, but I think #3 may pan out better for leveling... and might could even be made better.
