True, it does make you a walking tank.
Let's see, I'd have 8+(4+23) soak dice, say I eat an AP of -8, that leaves me at 8+(4+15). That's 15 Armor vs DV to decide if it even hurts, 19 Armor to decide if it's Stun or Physical Damage, 27 soak + 8 auto-hits, giving me an average 17 damage soaked...
Or 8+(4+23) vs -half, that's 8+(2+12), so 12 for Hardened, 14 for Stun vs Physical, 22 soak dice + 6 autohits = average 13 damage soaked.
Vs your Rocket: 10 auto-hits, 31 dice, so 20 damage average soaked without Edge, and it'd barely be Physical. Vs the Thunderstruck I'd have average 4+6=10 damage soaked.
