Is gnar's ult bugged or am I just fucking r%%%%%ed

Every single motherfucking time I play gnar, about 50% of the time when I ult people, they don't go in the direction I intend. They go 90* counterclockwise or clockwise of the direction I THOUGHT I cast my ult in. When I intend to ult them north they go west or east. When I intend to ult them west they go north or south. For example, last game there were 2 low hp people in their base, blue side. I e-flash ulted them, intending to ult them into the wall to the north. Instead, they went west. Stuff like this with gnar's ult has happened to me on a million fucking different occasions. WHAT THE FUCK IS WRONG WITH ME/GNAR
