This basically nullified the Night Elves' contract with Alextrasza, Nozdormu, and Ysera, or at least Nozdormu.
After the War of the Ancients, when the tree was first planted to prevent the energies of the new Well of Eternity from spiraling out into the Nether (not stopping it from bathing over the Night Elves' land. Quel'thalas was shielded with runestones to prevent the Sunwell's energies from spiraling out into the Nether too, that didn't stop it from bathing Quel'thalas), the three willing aspects each blessed the tree to grant a specific boon to the Night Elves.
Alextrasza blessed it with strength and vitality to give the Night Elves strength and vitality.
Ysera blessed it so druids could enter the Emerald Dream.
Nozdormu blessed it so the Night Elves would never succumb to death by age or disease, which makes for a strong combination with their strength and vitality from Alextrasza.
As you could see in Cataclysm, the Well of Eternity was still very much intact after Archimonde's defeat.
Not until Legion does it take a hit when attacked by more demons, but Nordrassil itself was untouched. The Well still has some water left, and the druids say there's still hope as long as one drop remains, so Nordrassil and the Well are fine.
So, yeah, the Darnassian Night Elves were every bit as boosted as the Nightborne, Shen'drelar Highborne, or High/Blood Elves.
Also, why is the high elves defending their kingdom a bad thing?
