The problems with archery now are the hard ways to aim or know when you're going to hit the target. I understand the aiming is something you want to keep, but I think adding a way to change the aim without first stopping aiming and then starting to aim again, hoping that now the char points in the right direction, would make archery A LOT better. So you could just simply make it so that first time pressing left click starts the aim, like it does now, and second time pressing it always fires the bow, and then you could change the place you're aiming by pressing for example ctrl+left click.
Another problem is that its hard to know where your char is pointing. This could be fixed by adding a line that points in the direction your aiming at. You could make it so, that the higher your MM is, the longer the line is. But this could make it too easy tough. But please at least consider adding the alternative aiming method, please!
