Honestly, at this point? I would just scrap magnetic and viral. Replace void status with combined version of their effects, making enemies more vulnerable to all incoming damage. Now your operator is a primer, reinforcing their combat utility role and making status amps worth using. I'm not sure what would replace mag and viral's effects, but they could stand to be more interesting - grouping for mag, maybe?
I don't know if I agree with increasing the survivability of corpus. They have always made up for their lack of survivability by being more disruptive to gameplay, via nullifiers, scrambus, etc. If their ehp is similar to Grineer, they will just be overall less fun. The intention seems to be to get us to switch off of viral/slash for them, but honestly, I don't want to switch my entire build every time I fight a new faction. I feel like pushing magnetic, viral or even corrosive as nearly vital to fight their respective ehp types is a key problem of the status system overall, and the primary contributor to limiting build variety. I believe status effects should be generally useful across all enemy types, and provide new and unique ways to build, as opposed to requiring corrosive to deal with armor, or magnetic to deal with shields. If magnetic has no effect against unshielded enemies, I will never put it on my gun, because I play varied content and I don't want to build to deal with only a third of it.
