Well Im frost DPS specced 13/51/7 and what i cant understand is the dmg of Frost Strike, is it also reduced by armor just like OB which is phy attack, because i tried to compare both of them OB and FS
With Talents from frost tree FS get bonus 45% dmg (im not counting Tundra Stalker because OB also gets buffed by it)
FS is 60% strike so when we sum up we get 105%.
Glyphed OB gives us 100% dmg and +5% from T8(4) bonus + 2x12.5% from diseases (running double disease rotation).
Now to compare 2 sigils
[Sigil of the Vengeful Heart] and
[Sigil of Awareness] the bonus damage to both of abilities is about the same.
In 6xIT rotation we are able to do ~7FS if im correct and full rotation takes about 17-18s
Im running double disease rotation IT-PS-OB-BS-BS (dump- its 2xFS) OB-OB-FS-OB-FS its done in blood presence and it takes about 17s.
What is not clear for me is the DMG that FS can do
[Sigil of the Vengeful Heart]
and also if its modified diffrent than OB
Also is the 8FS spam doing more DMG than 4OB+4FS? i'd like to know what dmg in % does sigil add to FS
cuz what i was thinking is 4xOB+4xFS *1.15 is (4x130% + 4x 105%)*1.15 = 1081%
and 8xFS = 8x105%(+the unknown bonus from sigil) = 840%
My question is: Isnt heavy OB rotation better with T8 Sets? OB has really high crit chance (~65-70%)
and its kinda more player friendly, what i mean is in unholy presence KM procs faster and in many ulduar encounters players are not able to focus on KM procs and also try to stay alive.
Here i present my DPS done at dummy in ebon hold with OB rotation:

and FS stats

As you can see im really high on crit with FS because the only 1 skill that may eat my KM proc is the IT which is used to apply Frost fever.
I ask about all that things because im in 10man riding guuild so im kinda not able to get
[Sigil of the Vengeful Heart] dunno, maybe i try to defend myself, and here is my armory link
