If a coming boss uses an attack like Nidhogg's Ahk Mourn that only targets the tank where he isn't hit with one single spike, but back to back heavy hits until the attack ends Excog could be useful.

Not really. You can just use Lustrate. If a one second recast is too short to handle such a mechanic, then no other healer can do it.
