I've been idly working on a Fighter Crossbowman archetype build, and it got me thinking. The archetype gets a damage bonus (+1/2Dex, then +Dex) when making a Readied attack with a crossbow. This is great and all, especially when you're focusing on the enemy spellcaster, since they then get a chance to lose their spell. But what about other characters? If you're setting up a shot (with a crossbow or anything else for that matter), waiting for a specific opening, shouldn't you be rewarded if that exact opening comes to pass? The risk is that you don't get to act at all, and you've basically wasted a standard action, potentially your turn.
So, what do you all think? Is giving an additional reward to a ready-er, like applying a circumstance penalty to an attack roll or skill check on the victim, seem appropriate? Is it overpowered? How bad of a penalty should it be?
I would play the rules as it was meant to be played. The game is a game of choices. You live and die by them. I would not give them a reward because they guessed correctly.
