Engineer's flamethrower inexplicably misses
I get this too sometimes but I always thought it had something to do with lag…
Any plan that involves dead quaggans is, by design, foolproof. I’m an unmitigated genius!
It’s very sensitive to your camera orientation, and has been around for a long time. Try to ensure that your camera is facing the targets you are trying to hit, and it should help flame jet hit more consistently. It also helps if you’re not rotating around so much while using it.
Alternatively, I believe if you just stand perfectly still and not hold down the right mouse button, your character should auto-rotate to a degree so that the flame jet gets pointed exactly at the enemy, but I’d have to test that to be sure. Obviously this technique would not be that feasible in most PvP situations.
