This soul is pretty much tailored for DPSs. While it would increase damage output, the downside is soul requirement.
The main DPS in the team should aim to have a Crit DMG soul set at 101% Crit. If Odokuro souls cannot fit into this set then I would still suggest giving up Odokuro and keep Crit DMG set.
Of course, if you are lucky enough to get high enough Crit on two Odokuro, by all means, try building into your Crit DMG set.
*2 set bonus only effective in PvE fights
Although the Unique Passives are not functional in PvP, the 1 set bonus does offer greater flexibility for soul composition.
