Unfortunately those logs don't have info on what levels we were, where we were xping, and such. It's ben a looooong time since we last used the parser, so I'll do my best to remember. The first couple of logs I can say, with certainty, were before level 30. (I believe the first is at level 22, hitting spiders in Korroloka, and the next would be spiders in East Altep at 25). So, the DRK didn't have a lot of their DD abilities, but the THF also didn't have TA either.
Once we hit 30 and the THF in our group did have TA, we would set it up so the DRK gained initial hate- but not with a voke. (DRK actually had THF sub, heh). Typically, we'd make sure we had full TP at the beginning of the fight, DRK would Sneak Attack and Power Slash to gain hate, then THF would SATA Viperbite (or Wasp Sting, earlier on) onto PLD Right at the start of the fight. After that, the PLD only had to voke once and we were set for the rest of the fight. (Actually, our PLD complained that his job was TOO easy with the setup we had- he never lost any hate before it died, heh.)
I agree that if we were to run the parser now, our THF would be behind the DRK in damage dealing, now that we're all getting to about 45 and have a lot of the cooler abilities.

In fact, even the DRK may be behind the BLM currently, who is starting to get the 2 line of spells. That still doesn't mean that the THF isn't cutting it anymore, though- if anything, with the shakeup we had at lvl 40 (changing PLD tank for WAR/MNK) he's needed more than ever. That nice damage he does is just icing on what the THF is needed for- hate control.
