Thanks for the fix zimeron, we are getting closer:
16,3 simmed (icc on) vs 17.7k live ( equip is the same but just herkuml instead of the deathwhisper trinket)
Once again, taking a look at the damage sources of SIM vs Weblog ( Saurfang HC 25)
Obliterate: 14.5k vs 13.7 k
Frost Strike: 9.5k vs 12.5k
So it seems as FS is still not implemented as on live. Going to ask my friend to do some test on froststrike doubledipping while copying a DK myself to the PTR. Maybe someone else can add some data?
Taking a look at other parses on WOL, you see, e.g., against General Zarithrian, rankings where people are hitting for 9.5k without the ICC buff.(we can assume that they also have BiS gear) so it does not look like Frost Strike is double dipping.
Could it be that the server has stealthbuffed the froststrike and the client / it's tooltip / simcraft do not yet know about that?
On live it says 110% damage, but, e.g., latest PTR Build tooltip says 125%. Can someone run some tests with different equipped FrostDKs on live, e.g., using different weapons and then see whether it really scales with 110% of weapon damage? Don't have one myself on live right now..
While looking at the issue, I have seen something strange on Live. When I'm not frost spec, the tool tips on FS is 110% weapon damage. But whenever I spec for it, it transform to 121% damage, just by selecting frost main tree without any talent.
That means there is a 10% bonus somewhere. Blood of the North - Spell - World of Warcraft
Effect #2 Apply Aura: Add Modifier - % Value: 10
That would be why yours and my sim have a low FS compared to WoL.
