Dynamis-Xarcabard
The damage range was anywhere from 500 on the PLD Demon NM to around 1200+ on the regular Demon NINs. The one thing I really liked is the fact that it maintained the range no matter what. It didn't matter if I was blinded or flashed, the 1x WS would connect without fail when stacked with SA or TA (something I'm not used to with DE's 5x or SB's 2x).
The Demons don't give me flashy numbers or anything, they're probably the hardest enemies I can test it against. I'll get some WS shots up to give you the DMG range though. They're better than what I can currently put out with DE or SB.
I only really took one action shot, the rest was a for future comparisons as log shots like the one above.
Dynamis-Jeuno
I did a Dynamis-Jeuno last night and was able to get a DRG 2AF that I was actually really looking for. While there I was able to test Mercy Stroke on much softer enemies than Xarcabard's Demons.
It's very hard to describe how neat it is to pop off the amounts above with just barely over 100% TP. Even TA+WS will break 1000. The ability to do that made my ready time much faster than normal. At some points I was actually still waiting for Either SA or TA to come back up for me.
It basically reminds me of the Gekko WS, but for THFs. Either SA or TA (Assassin) will make it connect on a non-PD target.
Ouside of Dynamis (Regular WS with a D39)
I can only do the regular WS outside of Dynamis, but I have noticed a jump in damage on those as well. The goblins/moblins hunted for the ENM stones were allowing me to place DEs inside the 2000-2200 range when fullstacked on THF/NIN onto our tank. It feels weird offhanding a Blau Dolch because it used to be my mainhand dagger. The speed is slightly slower than I've grown used to with Blau + a 183DLY dagger, but it matches my old Gully +1 in delay.
SA+DE on Apis was around 1000 with Sis Kebabis. The only shot I got of that was an Aura Steal though.
I'll get up other shots later when I can.
