... how deep in the healing water hole are you? Because if you're running like three healers (SSR Nike, Aphrodite, Andromeda while still taking care of the required debuffs with Ryu-Oh or something), then maybe. Having a large HP pool would allow you to not lose people from unlucky triple hits (though Water can bring Triton to prevent those).

But in general, you don't want to do that. As said by Kureru above, having long fights makes things more likely to go wrong. Also note that every point in Defender is a point less in Assault. Having a 80% Assault grid compared to a 120% Assault grid can easily mean a difference between a 7 minute T4 Accessory run and a 20 minute run. And you need three.
