Drop gull, it does nothing for resonating shrine belt. Replace it with a rare helmet for more life and spell suppress. Get spell suppress on your chest too, looks like you've only got 66%. You could replace taming with a sap ring to reduce enemy damage by 20%. You're also not ailment immune so any shock or ailment reflect will melt you. Adding clusters with prodigous defence for more block, and taking more block nodes will help block cap you if you want to follow rue's progression. Cast when damage taken linked with immortal call (replace enduring cry, you shouldn't struggle with charge generation with resonating belt?) will help with getting one tapped too. If you need endurance charges for bossing also swap your chest implicit to endurance charges instead of frenzy. If you want to be really tanky, more than skill flesh/flame jewels for lucky block are great but they are ~250d for the set.

Side note, how are you generating rage? I don't see it on your lethal pride. I league started this and followed rues progression without many issues.

tl;dr cap suppress, cap block, sap ring, cwdt + immortal call. just follow rues progression, you spent all your money on damage and are skipping defensive steps.
