No, it doesn't suspend my suspension of disbelief in the slightest.
Someone used a baseball analogy - sometimes a player hits more than one home run in a game.
All right, fine. How many games go by where the player doesn't hit any home runs at all? He still hits, but the ball doesn't go out of the park. I'd say that happens fairly regularly, too.
And how often does said ball player chose when he gets his home run? It's as much reliant on the pitcher as the player - the ball has to come at him just so. Maybe it's thrown from the wrong side. Or the player doesn't deal with certain types of pitches as he deals with others.
Regardless, for every game that involves two or more home runs, there's one that involves none. Not for lack of a successful hit, but because sometimes you don't hit the ball in just the right way.
And I assume it's much the same with a daily - yeah, maybe no one notices the Rogue who's crouched down and ready to murder a room full of people, but his victims might not be seated in such a way that's conducive to all getting nicked at the same time.
Or maybe he should be able to expend his used up Daily a second time...but by that same token, the DM should be able to go "Nope. You use your attack, but hit a patch of mud at just the wrong moment and the first target shifts in such a way as to deny you following up with anyone else. You just get the equivalent of an At-Will attack on him."
But instead of that, you get the opportunity to reliably say "I'm going to hit a home run." Yeah, it comes at a cost - rather than being able to hit two home runs in a game, you can just hit the one.
But it's a single home run. Every. Single. Game. It doesn't rely on the proper pitch, it can't get screwed up by a bit of dust suddenly getting into your eye, so long as you hit, that ball is going out of the park.
Reliability over randomness, with the cost being the number of times it can be used. I'll take that over a 50/50 shot (or whatever) of getting the maneuver off a few times per day...or having it fail and wasting the action.
Considering that a fight is a moving, hectic thing, I have no problem seeing a fighting-type only getting that one, perfect opening a few times out of any given day. But for every day that gives him three perfect opportunities, I'll bet there's any number that give him none - so it's a trade-off. Instead of three some day and none the next, it's one every day.
And that's fine by me and it is only a mild bit of reality-stretching, hardly anything to get worked up about.
