SAM and BLM got some buffs, which makes sense as a selfish DPS being at the top.
DRG needed some buffs to be competing with RPR. This update is a good buff for them. The change to tether I assume is because sometimes the DPS you give your tether to moves out of range and then you just lose your DPS buff as opposed to if you just gave it to yourself.
DNC got some buffs, which was much needed - even accounting for its support DPS by buffing others, the damage was still on the low side in rDPS. Now it's competing with BRD, so that's good.
PLD got some much needed buffs based on its DPS as it was lagging quite behind in comparison to other tanks. It's in a good spot now.
WAR getting a buff on Tomahawk is more like... WAR didn't really need any buffs, but here's a consolation to not feel left out until you get your dash.
Speaking of left out, rest in pieces, DRK and healers. White mage in particular needs a bit more buffs in its MP management in contrast to the other healers - just a bit more. Afflatus Misery's potency could also be bumped up to be DPS neutral too.
For DRK and the other healers, the problem doesn't really rely on potency as much as it does on gameplay issues revolving around its toolkit. Even if all the tanks got buffed, DRK's position in mitigation isn't as impactful as the other two in overall mitigation. In the event they want to keep tanks to be more tanky, healers really need something else to do outside of .. healing that does nothing at full HP with how many ways the tanks can restore HP? Don't get me wrong, I'm super happy that other jobs have more utility. It's just that ... spamming Glare/Broil/Malefic/Dosis because there's nothing to to do other than 1 button DPS when no healing is required will get very stale, and very fast. Hopefully it will be addressed in 6.1 though, as 6.08 was mainly potency changes.
