I use different loadouts for a few reasons...one of which is to rotate my kit and make the game feel less consistent and boring. As such, I select different weapons for different enemies for specific reasons and I chose the [Syam] for my Corpus melee because of its base 34% status chance. Corpus shields are weak to magnetic damage, sure, but why worry about that when you can apply toxin with a faction mod and double dip the toxin DoT effect?
We still take the magnetic dual status mods to take this build to end game, as corpus at higher levels don't all have shields and it's still a huge bonus against proto shields, which are beyond annoying to deal with. The dual status mods are used over the 90% mods because we still want toxin to be our highest damage status effect. This highest damage has the highest priority to apply, even if it's only a little. To compensate for the fact that the difference in numbers for which status effects will apply, we take Weeping Wounds to skyrocket our status chance into applying 2-3 status effects per enemy, per swing, and stacking as much of that glorious toxin as possible.

[Primed Reach] is used both to help stack combo counter for [Weeping Wounds], but also to take out nullifier shields as fast as possible from as far away as possible. We all know that feeling when the nullifier causes something to go wrong and we end up dying because of it...

[Condition Overload] is there as another multiplier on the base damage of our status effects because it will stack significantly higher than [Pressure Point] or [Primed Pressure Point] will. Higher stacks = higher numbers.
