Automatic firing at shields is broken

i think the functionality doesn't include apsis to reduce friendly fire (?)

I tested this with Ronin on one side and Aspis, Felon, Thug as the shield target.

Static positions with only enemy shield in range:

Felon: Ronin fires at shield (bad targetting at ground)
Aspis: Ronin doesn't shoot
Thug: Ronin fires at shield (bad targetting at ground)

Automatic attack move:

Felon: Ronin ignores shield as target and runs to death into Felon
Aspis: Ronin ignores shield as target and runs until Aspis is in range
Thug: Ronin ignores shield as target and runs until Thug is in range

So there are multiple issues here:

1. Ronin shoots at ground, but should shoot at source of shield
2. Automatic firing at big shields doesn't work
3. Auto attack move ignores firing at shields

It's not a rocket issue either. Here is a mace failing to fire at shields correctly.
