What are some recommended stats for T4?

The highest I was able to get this season was level 200, with enough armor and resistances for T4. But I had a really hard time also getting my health and damage up. I could barely do T3 because enemies took too long to die and I died in one hit despite my resistances.

What do people normally aim for in terms of max HP? I imagine a lot of the bonuses come from higher paragon levels, but how much should I still get from equipment? Because I'm afraid my damage will be even lower if I start rolling HP in the gear.

Any help would be appreciated!
