So let me see if I'm understanding this right
The Epoch, a plasma based and highly explosive support weapon with heavy penetrating properties and enough explosive force to gib yourself and send swathes of chaff flying and, again, able to BTFO factory striders, chargers, bile titans etc does NOT have enough demolition damage (aka the ability to pierce and blow up) to destroy fences, thin sheets of metal or collapse bug holes.
Is that what I'm supposed to get out of this? This is their intended and "logical" design for the weapon?
