DPS still unbalanced but it has nothing to do with the reasons of the OP.
We have had only a single day of Patch 5.0.8, so it is too early to measure the real impact of SAM and NIN buffs. However, SAM was not that much behind from DRG before this Patch regarding rDPS. The buffs should be enough to put SAM on pair with DRG. We will need to wait more days to see if NIN was able to get to DRG and SAM dmg level too.
Using the data we have TODAY we can say that DRG SAM and NIN seem balanced between each other. If we select data from only 1 Day on fflogs, we can see that for every Savage fight the rDPS difference from these Jobs varies from 200-400. It is even more balanced than the tanks damage, which is considered to be really balanced right now. MNK and BLM still ahead for a slightly higher margin. Again, I need to say that this is not a really good data since we had only 1 day after the 5.0.8 Patch, but at least is something to use in our discussion instead of personal experiences carried with bias.
Back to the topic, the DPS unbalance is not caused by the SAM and NIN situation. It seems that right now the Melee Role + Black Mage have a huge lead of rDPS ahead from all the other Jobs (Casters or Ranged Physicals). We can divide this problem in two parts:
1- Caster Role is completely unbalanced.
It depends on fight and percentile, but at high % (80+) BLM has an advantage of 1k-1,5k of rDPS in comparison to the other Casters (SMN and RDM). This is too much. You can argue about Ress Taxes and other things, but these taxes should not be that expensive. The Caster Role is the most unbalanced right now because of these huge gap between its members.
2- Melee Role is overtunned and Physical Ranged is undertunned.
It is known that MNK DRG and BLM were overtunned in comparison to all the other DPS jobs before 5.0.8. SAM was pretty close to DRG as a 4th rDPSer. All the other jobs behind them seemed really close to each other without really significant rDPS differences. However, after 5.0.8 SAM NIN and DRG should be really close to each other in the 3rd, 4th and 5th spot. However, since the SMN changes are just QoL and there was no change at all for RDM, DNC, BRD, MCH these jobs were left behind. This means that even the WORST melee DPS should be able to provide a significant advantage in comparison to a Physical Ranged Job (and other Caster Job that is not BLM).
A default DPS party configuration which respects the 5% bonus rule is: Melee + Caster+ Physical Ranged + "Anyone". In the current situation, it will be really desirable to set this "Anyone" position as a Melee Job because all melee jobs are in an okay position whereas all Physical Ranged and Casters (besides BLM) are really bad right now. Also, if we assume that getting rid of the Physical Ranged Job means 1% less damage, parties with Triple Melee or Two BLM are starting to be viable due to the really unbalanced state of the DPS Jobs right now.
