It would have been interesting during the final battle if destroying those Elder sarcophagi would have done something.
Negatively(health damage, an ability becomes limited, etc.) and positively(desperation leads to more brash actions and more dangerous abilities) affecting the Avatars being deployed. Stunning, frenzying, or outright killing ADVENT units and perhaps the same for some of the alien units. Creating psionic energy hazards due to the sudden death and release of their potent psionic energy.
More actively seeing the damage leading to eventual collapse of the underwater base. Water leaks. Panels beginning to cave in. Pillars collapsing. Etc.
Actually thinking about it, I could see destroying some being a side objective to ābalanceā the playing field if more experimental and aggressive Avatars were deployed. After the first one is destroyed, the others get a bit of a shield youāll have to chew through. To make things a little more fair, all take collective health damage when a sarcophagus is destroyed(including the Avatars.)
Also, potential death comments ranging from warnings of what is to come, disbelief of what is happening, more bargaining and making all sorts of offers(mainly to the Commander), and lots of long-winded cursing because they are sour prunes.
