Is this your health from buff > pets > buff? Or just Pets > buff?
At lvl 91 without the 20 life sc’s you should be closer to 4.8k life if you have the gear I think you do.
Either way, you’re on your way, just max out Oak sage asap and you should be a-ok (asap being lvl 97 if you’ve maxed the synergies)
I’d recommend sandstorm treks over Aldurs, and Magefist over Trang claws.
With 90 dex I’m guessing Ravenfrost + fcr ring? See if you can replace the raven with an Soj, being frozen only slows your walk speed, not cast rate.
Honest rating, 8/10 you’re almost there
