Anyone that thinks DRK needs a lot now is just wrong. The Last resort buff essentially makes them the strongest DD in the game outside abyssea , and a competitive one inside, unless you have a BRD/WHM + DNC in the party as well. If they really want to make a strong boost to DRK's magical side, they could boost Absorb spells. f they made Absorb Spells last 3 minutes and have the boosted stat remain static instead of decaying constantly, the effects would actually be worth casting the spells.

SMN has found its place in my opinion. You're a defensive support job that throws out supplemental damage. Earthen Armor with Scherzo is an amazing combo and is extremely effective for new NMs and Voidwatch. The fact you can solo well and have strong bursts of magic and physical damage types is a blessing people need to take advantage of.

PLD also has benefited. The addition of mobs that hit very hard, have high accuracy, and strip shadows, make them more desirable. If SE keeps the newer, more difficult fights churning out, we'll see PLD return in a real tanking role. The fact they made the recent VIT change was a precursor telling us of their intention.

THF is another example of SE getting it right. THFs wanted to be allowed to melee/DD on bigger mobs. SE made it so they would be encouraged to melee by making TH effects build as they do damage. To get rid of that pesky "THFs feed the mob too much TP" argument, they made AGI, a stat THFs have good amounts of, lower the TP given to mobs per hit, and release tons of good Subtle Blow gear, especially in slots that won't eat up Haste gear. The THF adjustment is probably my favorite adjustment as they fixed THF by not just giving boosts by damage, but by increasing its own unique way of contributing to groups.
