I think a Witchblade or Deathknight is better than Tactician despite the fact the the set was obviously made for Tacticians. I took a look at the Inq bonuses:
- 2 to Steel Resolve and Vior: Meh, these two are easy to softcap anyway.
- 12% armor to WoR: Good, but Blood of Dreeg or Mark of Torment is better for survival. It’s not the physical hitters that kill you with this build anyway.
- 1 Inquisitor: Actually meh, you only need a few support skills from Inq tree which are all easy to softcap.
- No phys RR
- The seal is useless as you are too tanky for MC (thus don’t need it) but would need to hit and run all the time in 150-170 (thus don’t need it either).
I think Octavius is a bit like Krieg, the latter was originally made for Battlemage but everyone chose to make Death Knights with it anyway.
