"Beyond" - 5th job second skill set

Some miscellaneous changes that interested me:

Cross Surge now gives 50% Final Damage as a passive, then gives 20% Final Damage as a buff, presumably like how it works now. I think it also reduces maxHP by 8%, but only up to a maximum of 4k HP. (This is not really a Phantom nerf, Phantoms now get 25% Final Damage from Piercing Vision and 20% Final Damage from Cane Expert, so after you max Cane Expert, it's pretty much the same, but you can replace Cross Surge with something else if you don't mind not having the extra 20% final damage).

Current:
Cross Surge, Final Cut
1.8 * 1.4 = 2.52 (252% final damage)

Revamped
Cross Surge, Final Cut, Piercing Vision, Cane Expert
1.2 * 1.4 * 1.25 * 1.2 = 2.52 (252% final damage at full HP)

Final Cut, Piercing Vision, Cane Expert
1.4 * 1.25 * 1.2 = 2.1 (210% final damage)

I wonder if any buffs be able to make up for the 42% loss in final damage if not using Cross Surge??
