To be fair, Deathwing was Aspect of the Earth, granted by Azeroth’s big wigs, so he has a magical affect over the planet’s environment.
They couldn’t really do much more, cuz they’d pretty much have to redesign the entire world again; in order to mirror the kind of damage that sword theoretically should have done.
They should of did that, come to think of it.
Something tells me that they kinda know about it, and it is gonna play a bit of a big role with this being from the TWW cinematic.
Yes, Deathwing swept across the entire world of Azeroth from Kalimdor to Eastern Kingdoms. Sargeras sword was large enough to have been felt across the entire world, but it is a sword - it is concentrated into one location, and that location still caused Azerite to start bleeding from the ground across the entire planet.
Yes, Deathwing had a bigger impact… because he literally flew across the entire world. Hell there’s even an achievement for that:
This used to be a feat of strength (not sure if it still is) and… yeah, he flew around the entire world. Which is what caused the Cataclysm when he broke certain geographical features by his presence.
Sargeras sword was devastating… but it was still just a sword once neutralized which is what we did when we gave up our artifact weapons, a dangerous one to the world for sure. But it is still just a pointy (sort of, but at that scale it is more blunt force rather than slicing or stabbing) stabby-stabby essentially.
What sword?
What sword?
We’re waiting for a giant king Arthur to pull it out.
Deathwing literally broke THROUGH barriers separating the elemental plane INTO the physical realm and out through to the planet causing massive chain reactions of natural disasters as well as the breaking of the World Pillar. Of course the Shattering was more of a drastic change lol.
They’ll remove it during the last titan.
Sargares will come back but on our side, and he will remove the sword.
That’s my guess
They never forgot it. That was a joke that Ion told in an interview with Asmongold and true to form Asmongold faked a dramatic reaction to up his click count.
according to Ion, there is no sword. I have no idea what you’re talking about. 
Oh my, Mr. Chekov!
i just think it’s a neat little artifact of our adventures in the days of yore. much like the dark portal. we need to make it a UNESCO world of warcraft heritage site for future generations.
We could mine it. That metal has to be great for making weapons and armor.
Sargeras knew exactly what he was doing when he plunged the sword into Azeroth, and that said, it’s a missed opportunity that we haven’t been able to explore the edge of that sword in Hallowfall or the other underground zones.
What sword? 
Wutyamean ?
That sword destroyed the next 2 expansions.
That impact should have been an extinction level event lmao.
Like worse than the asteroid that hit the dinosaurs.
bro mustve not paid attention in bfa, that sword was causing azeroth to gush blood everywhere like she got slapped by a arms warrior
He was also personally touring the planet destroying stuff.
But I see the other guy’s point. The speed and size of that sword would’ve caused insane damage upon impact…in reality. In Azeroth, it can be waved away by magic.
