Based on the lores of heroes, there are pretty damn much scary,ultra powerful being ( 4 Fundamental, AA, Elder, ES, 3 spirit, Weaver, Bane, Void...)
now consider the power of the battlefield
Enigma, consumers of planets, ultra-powerful dude, his black holes was a tiny bit of black object that sucks stuff on Dota 2 battlefield
Elder, shapeshifter of the World, who created every plain of existance, can only shatter a tiny bit on the Dota 2 battlefield
Zeus, god of thunders, even though lost his immortality, still just an old short little dude on the battlefield of Dota 2
The question is. What plain does the War of the Ancient actually take place? And how that plain could sustain so many black hole, so many battle, and still does not change a bit for a whole lot?
