When Last Stand doubles a unit's Might, does it also double the unit's current HP, or does existing damage remain the same?

Ruling: Last Stand doubles the unit's Might, but existing damage on the unit stays the same. Do not think of it as HP being doubled.

Sequence:

• The unit's Might value is doubled
• Any damage already on the unit remains unchanged
• The unit dies when damage equals or exceeds its (now doubled) Might

Nuances:

• Units have Might and damage tracked separately; HP is not a separate factor to consider
