Projectile does not Align with cursor.

Not sure if reported but this is just from my own observations

As a Simple test
occultist / ranger / merc

aiming left and right on screen your projectiles do not align with the cursor
it is above the cursor

casting contagion on occult even when hovering over a mob you can still fail to cast on that mob when clearly it is the one you should be afflicting specially in dense crowds

Ranger seems to have an even higher mis-alignment while shooting left or right.

you only seem to match cursor while aiming 90deg and 210deg.

Not certain this is intentional but is most certainly unpleasant.

When you click on the ground, the projectile aims so it passes above the ground at that point. Imagine you're aiming at the feet of enemies and it makes sense--draw a line between your feet and the feet of the target, and click on the ground on that line.

Some skills like gas shot do aim to actually collide with the ground.
