It looks like PLD is going to be doing the same exact thing as in SB... but will need more buttons to do it.
Instead of GB>RA>RA>repeat, it's GB>RA>Ax3>repeat, which takes 1 extra keybind
You still have your Req window, but you replace the last cast of HS with a stronger spell that takes an extra keybind

This is a real bummer to me, because I found PLD to be a real bore when mained, and these ShB changes don't actually do anything to change that. I guess I'll have to settle on DRK or GBR
