Eh, given how the alternative is 'everyone gets massive armor and then nobody fears an army of weak gangers', I'd say this new mechanic is more real Shadowrun.
I don't think anyone would argue that the soak
potential in 5e was extreme enough to be unbalanced, but wearing a decent ballistic vest, getting shot with a medium power pistol, and it doing nothing to protect you from the wound is lolsy at best. There is certainly room for a balanced medium.
Be prepared for the 9 body 1 strength troll overlords.
Bearing in mind I have not seen anything more than the QSR, I have a theory that a mystic adept troll with max body, increase body, armor spell, and mystic armor adept power will be the new tank. Maybe even drop that essence some for soak ware if the goal is maximum soak. We'll see if the final mechanics prove me right or wrong.
