It most certainly could, but i don't see any reason to make human siege even more resilient

. Imagine a siege rush with a mech shielding the ballis, there's no counter gonna work then, until lair dies (10 seconds later

)
@Feathers: Launcher could work vs Glider of course. We could make it push the Glider back too, at impact, since it's not touching the ground

.
It would be cool if the mech could actually counter blaze (since it has low HP anyways). Some kind of mobile shocktower that can be activated to protect other siege units from being blazed.
Well it can block it

. You can't rly kill a lego with blaze if he's blocking, so you can say the Mech blocking (using the 2 red generators to put up a shield in front of it) would counter blaze. But only frontally.
