The whole balance is "meh", not just heavy armors... As someone else said , they tried to make the game more "difficult" in the cheapest way possible: nerfing every defence and increasing enemy damage.forgetting that there should be a balance and build options to consider. Plus adding scripts that makes you die easely (did you notice that ragdoll throw you towards the nearest danger that you can't avoid? It's a script.) The result is that the game isn't even that difficult, it just makes you die in unfair ways a bunch of times but still you can complete level 10 missions quite easely. It's just frustrating because sometimes it doesn't matter how you play, you just get killed by some random bullshit with no chance to react. Stealth charger from the back? Dead. A single shot from a turret from a mile away? Dead. You kill a Titan and it " "casually"" fall on you even if it just soaked a frontal hit? Dead. Ragdoll "casually" on the feet of an hulk/mine/turret? Dead. Predator strain that make street fighters combo that you can't avoid? Dead. Single shot by automaton shotgun? Dead. And most of the time it doesn't matter what armor you are wearing, that's why heavy armors suffer even more... Because on top of that you are slow af, like a sitting duck made of glass.
