Zoe Q issue?

I spent a little bit of time screwing around in practice mode with her to get a feel for Q and learned a few odd things. Indicator for 2nd cast when first cast is still traveling is different from indicator when it stops motion and holds in place for 1 second. The hit box for It extends in odd ways, first cast has a smaller hit box then second cast, you can hit a small distance farther off second cast in a straight line forward or behind then forward then just casting it straight. You can hit even farther then this by casting it diagonally then recasting it to the exact same target that would be unreachable from a regular straight line.

The Q projectile moves in proportion to her hitbox or in simple terms WHERE SHE IS and that distance is always dynamic, so if you shoot backwards but move fowards you can increase the distance and you can test this by just flashing and ulting fowards. You might have caused the short distance by forgetting that it moves with her hitbox so maybe you shot but dodged something or just decided to walk backwards where the shot would come short.
