When Caduceus split his damage is halved, a Hoodswing Auto will barely take off 3k HP in Sword Oath with no stacks.

Mini ADS only deals like 1.5k damage per hit up to 2.5-3k at 3 stacks in Sword Oath.

And the above 2 scenarios the raid isn't taking any damage so there is no reason the dedicated healer cannot handle 3k heals per 2.5 seconds. Heck even precasting Cure 1 on my Shitty Whitemage would have topped it off.
