This is the current build I am testing. For all of [Inaros]'s tankiness, status effects can be super annoying. The Negation Swarm augment provides the same level of protection against them independent of its rank, at the cost of additional armor consumption per effect prevented.

I'm currently testing two variations of this build:
1) Rank 3 [Hunter Adrenaline] and rank 2 [Gladiator Resolve] vs full ranked versions
2) Unranked negation swarm vs rank 3
3) Rank 5 [Hunter Adrenaline] and rank 0 [Gladiator Resolve]

To avoid adding a fifth forma for negation swarm, I'm trying to settle on one of the three variations above. I'm leaning towards option 3, which is the current build. The loss of additional health is not that big a deal with all of the defensive mods and arcanes.

The other alternative is ditching [Stretch], but the extra range for his 1 and 4 is nice. [Rush] is a QOL mod, but personally I enjoy playing him with a little extra speed.
