Nomad Armor isn’t meant to make the class be able to face-tank by itself like Inflitrator or Gunner. Nomad’s primary sources of survivability is by indirectly tanking via Fearing/stunning enemies to not shoot back, or being outright invincible while Executing. If done perfectly, the class doesn’t technically need any other damage resistance.
HOWEVER. What Nomad Armor then does is allow a little extra breathing room to make use of Nomad’s abilities. Whether it be simply forgiveness for mistakes and providing a little room for error, or even letting someone use the class a bit more recklessly, which for aggressive players can be fantastic. Basically, use it to help get Executions that you otherwise wouldn’t, allowing you to make even more use of the CQC Fear stuff.
Plus, regarding the late-game poisons for increased enemy damage in Horde? Be sure you perk up Health as well as defend taps as much as you can to gradually stack up even more health. That potential 150% total combined health makes the 32% damage resistance spread out and stretch farther.
Enemies doing a third less damage is no joke for a class that doesn’thave to get shot to begin with, particularly for rapid-fire weapons. Most enemy attacks that could 1-hit down you are pretty avoidable and the Stim will protect from most of those anyways.
This is also not a bad combo depending on what you are using it for or with and if it fits your playstyle, then sure! Nomad can be played in a large variety of ways.
By all means, try it. Gnasher serves much better and easier against big non-boss enemies than Bleed usually does (though it has it’s uses, don’t get me wrong), and I would say that the best place to test out Nomad Armor first would maybe be Escape against fewer enemies at a time.
Anyway psst… have you seen the vid I made relating to Nomad?
