Was that your build when you were leaning on Wolf and Saint, or now that you’ve abandoned them?
That class mod might be handy when you’re nursing your wounds after a fight, but while that 55.5% is respectable (seriously, that’s pretty high, right?), I’m not sure it’s enough to tank you through a fight? Do tell if it can carry you through some fire or corrosive DoT (not with your shield up; straight off your health meter). Anyway, I might replace that with one that at least buffs some of your skills as well. It’s hard to beat the Celestial Enforcer class mod, but it’s also difficult to find, but even a blue rarity one from a vending machine (of whatever ilk you like) may have better returns than your current.
Is your kit the Invigoration Oz kit? I ran with that in early playthroughs until I had enough skill points to stand on my own two feet, but that kit kind of only works in a vacuum (where you’re constantly consuming oxygen and therefore Hoovering up all kits/health). In atmosphere, your oxygen replenishes so fast that it’s hard to pick them up… you almost have to slam down onto them and hope your oxygen didn’t top off before you land. Are you using a different one in atmosphere? You may get a lot of advice about using the best legendary Oz kits you can find (and some of them are pretty awesome), but in a vacuum, that Invigoration kit is no slouch for keeping your health topped off.
I generally roll with the Hunter Killer tree almost maxed out, which is almost certainly the reason I can fire and forget with Wolf.
