I never brought that up in the first place.
I never made this claim either. But let’s go over the key points.
- World Trees are not, by their nature, fireproof. We know this thanks to Nordrassil, Teldrassil and the unknown World Tree that existed in Ungoro Crater. Nordrassil was burned by Archimonde’s death (but not destroyed), Teldrassil was burned and destroyed by the Horde and the unknown world tree was burned to ash by a volcano that erupted beneath it.
- Both Nordrassil and Teldrassil were blessed by the aspects, only one aspects blessing matters in this case however, which is the one given by Alexstrasza. This blessing increased the strength and vitality of the tree. Neither Ysera nor Nozdormu’s blessings enhanced the strength of the tree.
- By the time of the Cataclysm Nordrassil was not blessed by the Aspects. The blessings had been sacrificed by Malfurion Stormrage during the events of Warcraft III and Alexstrasza never blessed the tree again, instead belatedly blessing Teldrassil during the events of the novel Stormrage.
- Only Nordrassil has its roots feeding on the second Well of Eternity.
It’s easy to conclude that Nordrassil has enhanced strength over the other two, not by Alexstrasza’s blessing, but by the fact that its roots are feeding on water from the second Well of Eternity.
Moonwells are, as you can tell if you literally walk into one, very shallow and the roots of Teldrassil do not touch the waters within those wells as the wells are made from stone and wood, not earth.
