Whole teamfight is a trainwreck. I get it.
That's why I tell my team every time I play Sion that my ult is purely for "Zoning" purposes.
I wish it was that epic.
Holy crap... Is that real or edited/planned?
It looks like a crash test. They do those with all kinds of vehicles, not just cars.
Ah, yeah, I see the people watching in the background now.
When you hear sion scream just run and pray he doesn't hit you with his ult.
sion can miss an ult?
Yes, whenever the enemy team doesn't have 5k ping
