Help my build survive lots of small hits before event starts (shield crush jugg)

My build: Level 92 Hybrid Crit Shield Crush Juggernaut [3.25]

Guide I'm trying to follow: Level 95 Hybrid Crit Shield Crush Juggernaut [3.25]

A bit broke version, since Aul's is hard to get in pohx's event - so no pride. Also tree pathing is a bit awkward, since without getting enough reservation efficiency to fit in tempest shield my char gets dead real quick.

Build feels pleasantly tanky, can facetank T16 bosses no problem, but I am having issues with lots of small hits (like eater mob packs with these nasty blue projectiles or goatmen mages). Would getting recoup on rings help with that? Maybe I could fit in steelskin? Any other suggestion?

Thanks!
