DNC's Honing Dance, but longer channeling time. Just give me a button that I press once, spin to win, then not think about pressing any other button for like 10 seconds in the middle of a huge group.
GNB's Draw and Junction but tweaked to where it adds beneficial effects to just Heart of Light depending on who you tag in the party. Tank = Adds party-wide shields, DPS = adds to party : Bloodbath effect + Knockback Immunity to whatever Arm's Length or Sure Cast can negate, Healer = adds a mini Excog to party in range that instantly restores like 10% or 15% of max health when dropped below 50% or when timer runs out.
