PLD - Skills in numbers - Does anyone have any clue?

Bloodbath heals you for 25% of the damage you deal. Healing has a 0.5x enmity multiplier according to Immut. So, 12.5% of your damage is converted into enmity. With Shield Oath up, that's 20% (using the 1.6x figure). This does not affect Flash.

Also, looking at it, your Fast numbers are totally off. It gets NO enmity multiplier. Also, your Shield Oath numbers don't take the -20% damage penalty into account. So, using your example, the numbers should be:

So with 100str, 100det, 100crt and 30 weapon damage I should do raw:

39.80375412 Fast
55.72525577 Savage
68.99317381 RoH
132.6791804 Flash

Enmity. If it is multiplied by the enmity changers it gives:

39.80375412 Fast (Bloodbath: +4.975 = 44.779, a 12.5% increase)
167.1757673 Savage (Bloodbath: +6.966 = 174.141, a 4.1% increase)
344.9658691 RoH (Bloodbath: +8.624 = 353.590, a 2.5% increase)
132.6791804 Flash (not affected by Bloodbath)

And with Shield Oath:

63.686006592 Fast (Bloodbath: +7.961 = 71.647, a 12.5% increase)
267.48122768 Savage (Bloodbath: +11.146 = 278.627, a 4.1% increase)
551.94539056 RoH (Bloodbath: +13.798 = 565.743, a 2.5% increase)
265.3583608 Flash (not affected by Bloodbath or shield oath penalty)

EDIT: In conclusion, the effect of Bloodbath is negligible at best. We're talking about an enmity change from 883.113 to 916.018, a 3.7% enmity increase, across each combo performed while under Bloodbath. If you use Flash under Bloodbath, the number is even lower.
