Before regen:
* Any damage you did stayed unless they devoured or mutated around it.
* Wounded units stayed wounded, easier to finish later.

With regen:
* Units that take minor or medium damage but then get out of your fire: - Gradually heal back up.
* Over time, all non-finished damage in low-pressure areas: - Disappears.

So:

: 

===== Their 100k HP force fields: =====
* Used to be a one-time buffer.
* Now: - If a unit pulls back from the front and waits long enough, - The shield can slowly recharge.

That means:
* They can rotate units: - Freshly shielded ones to the front, - Damaged ones to the back to regen.
* Over long battles, shield integrity across the swarm stays higher.

===== This regen stacks with what they already had: =====
* Devour: - Big heals / evolution from eating corpses.
* Regen: - Constant slow healing even without eating.

So now:
* Devour gives bursty healing and growth.
* Regen gives baseline maintenance, constantly undoing your lighter damage.

Mutation + hive mind will likely:
* Evolve forms that: - Retreat at the right times, - Maximize survival just long enough to regen and come back.
