Dunadd i see your point, but the testudo HAS to be effective or there is no point in it being in the game. It was a good tactic that did pretty well at neutralizing the heavy ranged combat that Rome often faced. What this mod will hopefully do well i simulate the fact that when the romans were prepared, they could face any type of ranged army and win most of the time. If caught unawares, or tactically outmaneuvered, they were toast. The mod should do this fairly well from the descriptions here because ranged units hitting from the back and side are still going to be extremely dangerous.
