I also think that the current aiming system is not ideal for ranged weapons because when the monster moves laterally across the arena, your camera moves too, but you have little way to tell how much the monster moved unless you’re also taking your sight away to look at the background foliage instead of observing the monster. This makes it difficult to track the monster and shoot ahead of where the monster is going to move to.
Take Banbaro for example. After it does the vertical head slam, it will swing its head to the side. There is one point in space where if you keep aiming at that spot, your shots will connect with the head regardless of how the head moves. However, because the camera moves slightly with the monster’s movement, end up your shots are not actually going where you think you’re aiming at (or, rather, you’re not aiming at where you want to actually aim at).
I proposed to add a full unhinged aiming mode here so that we can truly aim like an FPS game: Add a full unhinged gyro mode and adjust how dodging works
If you think this is also one of the contributing factors to the ranged weapons not hitting where you want to hit as the monster moves, please consider voting for it too.
