Shields are better against arrows

[Puzz3D]

Ok... We have ever since the first reports of the game suspected that the shields are somehow more effective than their mere stats seem to indicate.

I did some tests in custom battle of basic foot archers vs hastati in RTW v1.2 and RTW v1.3. I only observed a slight difference in kills/volley, but I did see something that would lower the kills in RTW v1.3, and that was the archers only used 2/3 of their ammo in v1.3. As a side note, the rate of fire has been increased in v1.3.

The archer is AI controlled, large units (80 men + 1), flat ground, max range and the hastati are in the default 4 rank formation. I did a couple of tests in each version.

RTW v1.3: 28 kills in 145 seconds with 20 volleys
RTW v1.3: 29 kills in 145 seconds with 20 volleys
RTW v1.2: 37 kills in 255 seconds with 30 volleys
RTW v1.2: 40 kills in 255 seconds with 30 volleys

The archer has 30 ammo in both versions, and after 20 volleys in v1.3 the archer charges, but stops and shoots 3 more volleys at short range before engaging in melee. So, it does have more than 20 ammo, but doesn't use it all at max range.

The rate of fire is 8.5 seconds/volley in v1.2, and 7.25 seconds/volley in v1.3.
