The only reason i'm saying the auto-block mod could work is it seems to have something similar to the old block relative to enemy position setting you can use.
The old "Attack Relative to Enemy Position" wasn't automatic. It just required less twitchy movements. You look to the left of the enemy, you always swing/block left. You look to the right of the enemy, you always swing/block right.
As some one who's hands shake, my current attacks are all over the place. I sweep my mouse to do an overhand attack? My hand shakes just a tiny bit and lo and behold, I end up doing a right sweep. Go to block a left sweep, again, my hand twitches, end up trying to block a stab. If they added a dead zone to the attack direction select it'd be fine as well. Its VERY twitchy for me, practically jumping all over the screen. But the old system basically had it where if you're looking one direction, no matter how you moved your mouse on that direction, it would attack from that direction.
