15 STP vs 10% DA
TP
/SAM: 15 STP will add 1.65 TP per hit. (Caladbolg)
/WAR: 10% DA will add ~1.1 TP per hit on average. (Caladbolg)
WS
/SAM: 15 STP will add 2.25 TP to Resolution's TP return. (Caladbolg)
/WAR: 10% DA alone gives a 41% chance to proc at least 1 DA with Resolution. Atheling, Pole, and Brutal will bring that to 67%. Avant Gauntlets +1 and Jingang Greaves will bring that to 75%.
Other Notable Stuff
/SAM: Meditate, Sekka, Hasso, Third Eye, Zanshin
/WAR: Berserk, Warcry, Aggressor
With VW COR rolls, temp items, uncapped acc, uncapped att, and hasso being a lot less useful now, /WAR is looking pretty good IMO.
A few things to note:
DA can only proc on the first two hits of a WS, so there is actually only a 19% chance for DA to proc at least once on Resolution with nothing else, a 36% chance for it to proc with Atheling, Pole, Brutal, and there is a 42.2% chance with Avant and Jingang as well.
In response to Hasso, it is 10% JA ability haste, but unfortunately does not stack with LR.
In one hour a DRK with Caladbolg and capped haste in gear with 0 DA and no haste cast on them swings 669 times in one hour. This goes up to 911 times with only using LR (assuming fully merited).
If they are /WAR with no haste cast on them and 0 DA gear, this goes to 736 (no using LR) and 1002 (using LR).
If they are /SAM in same circumstances, 772 and 940 respectively.
So in a more organized formate:
/??? - 699 and 911 LR
/WAR - 736 and 1002 LR
/SAM - 772 and 940 LR
If you factor in 10% DA in gear for TP (Pole, Atheling, Brutal):
/??? - 736 and 1002 LR
/WAR - 802 and 1093 LR
/SAM - 849 and 1034 LR
Now if they receive haste and have 10% DA in gear:
/??? - 914 and 1383 LR
/WAR - 997 and 1508 LR
/SAM - 1096 and 1434 LR
Ideally, a DRK should be riding LR, and most good VW should be over before or close to when LR wears off. However, these numbers to not compensate for STP and WS frequency. It would be alot of work to factor in all the STP, Regain, Save TP, and dusty wings from VW, and I really don't feel like trying to math all that out. Anyways, my money would be on /SAM due to the STP for WS frequency, zanshin and hasso because some VW mobs can be evasive, and meditate and sekkanoki are handy.
