The problem with resolve is that gives you a bonus that has increasing returns (deflection), so the difference between a few points of resolve could literally mean infinite survivability. In party play, where damage is much more spread out, increasing your Con might do more with respect to increasing your survivability. That said, this may be more true in solo play, where fights tend to last a long time, and the effects of any extra “padding” a high Con provides has little effect - if you’re going to be taking several hundred points of damage over the course of a tough fight, padding your HP by another 20 points or so isn’t going to make much difference.

As a rule of thumb, if you can’t sirvive a challenging fight with a 10 Con, then you won’t be able to survive it with an 18 Con either. But I’ve found Con to have little impact on this you need enough Con to ensure that the little swings in randomness that perturb your health don’t kill you, but other than that it’s not of much use. You can change various variables here by (say) increasing the speed with which you can take them down (DPS), or by giving yourself more time by improving damage mitigation or healing. Either you have a balance of damage mitigation (AR/deflection/defenses) and damage recovery (regeneration, healing) that balances out the damage done to you for long enough for you to take them down, or you don’t. Maybe my focus on solo runs biases my experience, but I’ve never found Con to be of much use tanking.
