The camera should NOT zoom out if the player keeps the right mouse button clicked after firing the arrow, its extremely annoying have the camera constantly changing focus when firing multiple arrows this way. It really should be changed ASAP, it is probably the worst mechanics on archery right now.
While speaking on powershot it would be really nice if we had a different animation, rather than a sparky arrow when its ready. For example, the character pulls the bow string and aims, once the powershot is ready, instead of having the arrow blink maybe the character would pull the string even further and assume another pose, displaying the powershot is ready. Would also be more immersive and pretty this way.
