Unless I missed something in a recent update, pulse grenades have never drained shield like this, they drain ammo and temporarily expose dekas to hull damage. Watch the slow motion clip that I provided and you will see that the shield is lost after the proj shot, not the pulse grenade. And if it was the pulse grenade that drained my shield from max, why did it not also drain the shield of the deka next to me? Also, if this was an intended feature, don't you think this would be extremely unbalanced? One pulse grenade drains max shield? Deka would be borderline useless.The shield was discharged by a pulse grenade used on deka nearby, this is not a bug.
