Reduced Shield block chance for most skirmisher units as before they survived too much for what they did. Peltasts were very OP.

Reduced shield block chance for pikemen slightly as they had turned into walking tanks of doom.

Raised thracian shield block chance from 0% to 10% once I found out what units use them

Reduced shield block chance slightly for hoplites. Hoplite shields have the biggest armour boost and the block chance I had given them put them almost on par with roman shields.
