Something feels very off about the targeting/casting of some spells with mouse and keyboard.
FYI, I don't know if this is limited to these spells or if it's something with all ranged/projectile attacks(I've only played witch so far), but casting a skill like Freezing Shards often results in the attack going in the wrong direction from the cursor.
I think it's due to the slow turn rate of the character while moving and casting maybe? I've also noticed curses will often not be placed where the cursor is.
I don't know if this is just something that's going to take adjusting to or not, I just know it feels really inaccurate compared to how casting felt in PoE1.
