As soon as it falls off, the other healer gets afflicted with it. Healing in Ifrit EX forces the healers to manage quarantining themselves away from the group and thus cannot AoE heal easily during that time, and is made more complicated during nail phases where the party needs to run around the room destroying nails.

Leviathan EX had Briny Mirror. That was also a debuff that Leviathan would place on the off-tank and would be reapplied to have 100% uptime on the second tank. Every time you heal that tank, even if through AoE heals, hits you with a stacking debuff that gradually reduces your casting range and spell radius, which also shrinks the size of your AoE heals. If you heal that tank too quickly, you'll have so many stacks that you literally cannot heal anyone but yourself as your range and AoE radius become 0 and you need to wait for that debuff to fall off to heal again and would need to work with your cohealer to manage those stacks to prevent them from getting too severe.
I remember there was a way to Cheese Leviathan by having the healer get enough aggro to trick the system into giving them the debuff. I know I've had that debuff several times in the past before the offtank when I was a healer, that it made that fight infinitely easier since Regen/Fairy abilities didn't build up stacks so for the first minute or so, you didn't have to worry about healing either tank.

God I miss those days
