If an archer (or spellcaster) is confronted with a bruiser standing next to them and doing nothing on their action (or obviously 'readying', since I believe it's supposed to be apparent when a charcter readies an action), the smart course of action is to perform a double move, not 5' step back and fire. Because that's what the bruiser is waiting for. This is assuming the bruiser is considered a threat, of course. Sure, you didn't get to destroy anything that round, but then neither did the bruiser.
