PLD's casting time of Holyspirit also got buffed from 2.0 secs to 1.5 secs.
It might not seem like much, but the shorter casting time means you can effectively get 1 extra-additional Holyspirit under the 20% ResQ. Buff, which is yet another seizable DPS increase, in addition to more autoattacks inbetween the Holyspirit spam.
