on my Fire Sav i've been using the Fireball SLA fairly frequently and i've noticed that when i have nothing targeted it wont go in the direction i'm looking, it always goes in a direct line away from me at. never hits the ground when i'm aiming straight down, never flies away when i'm aiming up, always straight ahead unless i target something
is this a bug? i dont remember the actual spell ever doing this, but then again i never really used the spell as i always went for Acid Blast instead (overcomes more resists). but even with acid blast which i always used at lower levels, it never flew parallel to the ground when i didnt target something, same with Otilukes Freezing Sphere and Ball Lightning
might be something for Devs to look into
