Red Lotus, Phalanx and War Drum given back to GLA/PLD (they were old 1.0 abilities that disappeared with ARR) - although something tells me Red Lotus is being kept in reserve for RDM. *sighs*
Maybe even the old version of Rage of Halone (five-hit attack instead of just three hits).
And some low-level healing spell for GLA/PLD specifically that Clemency replaces at high levels, as there is so much older level-synced content that assumed you were cross-classing Cure (potions are not a sufficient replacement).
