In my opinion; Seath gives little reason to wear heavy armor. He does such heavy physical damage that you generally can't survive that many hits anyway, while his magic and curse is just as effectively blocked by lighter armor sets like the Dingy Set.

If you have spare attunement slots, I'd recommend trying to throw some pyromancies into the mix. Considering your weapon, Great Fireball is probably your best bet, although it's up to you.

Just my opinion, but it's worth giving it a shot.
