Ok, this has been eating me away from some time now. During the Battle of Naboo when the Battle Droids break through the Gungans barrier, they open fire. Yeah. So, how come when their shots riochet of the gungans riot-like shields, they don't even phase the Droids? When Qui-Gon and Obi-Wan deflect shots back at the Droids they go down. Why wouldn't the riochets be any different?
