Witchhunter Sorcery ward question

Im starting to tinker with making a Sorcery ward witchhunter build for next league since i want a crossbow build that also feels tanky. I wanted to know how noticeable is the DoTs going trough sorcery ward and if its necessary to build life to survive those DoTs or if i can get trough with ~1500 life + ignite immunity and poison/bleed charms. Also bonus question: if i do Chaos Inoculation (bleed+chaos immunity) + Ignite Immune + Sorcery ward, is there something that will still go trough the shield and oneshot me (are there non-bleed phys dots, cold and lightning dots or non-ignite fire dots in the game?)
