In my house rules you Can dodge a ranged attack, IF
1) You Spend one Defensive Action, non-refundable in any outcome
2) Succeed in a Perception Roll (-20%) [it's moving fast and hard to see]
3) Make your Dodge Roll (-attacker's Crit %) [some people are better at reacting to movement and target prediction, skill dictates]
4) Go Prone [edit : or in some rarer cases, dive behind cover. Remo and Neo need not apply]
In that order, no take backs, etc.
Seems hard but reasonable, and makes the action mighty Heroic.
