You mean like 360 so it can absorb 2 ATG or tank shots but not 3 Schreck shots or 4 Fausts or 1 ATG + 2 Fausts?
I mean Im nothing to write home about but its better than the (what is it 320) health it has currently.
EDIT: Dont forget, with the patch the quantity of Schrecks should decrease slightly so we should take that into account but this also highlights the fact that we could also change the damage of them.
The T-70 Shouldn't be hard to kill but god damn should pack a punch due to its low health,armor, and often bad pathfinding.
