Kamikaze Midget said:People using the first approach probably would say "Jack Sparrow is no Rogue!" As hong points out, rogues are pure 100% ninja. Cap'n Jack doesn't skulk, sneak up, and stab you in the back like an assassin in combat.
But he would if he could. However, having no defenders to keep the enemy from focusing on him, he gets trapped in straight up, one-on-one(-on-one) fights and cannot sneak up or sneak away. He's too much of a target for EVERYone.
Just because he doesn't have the opportunity to do something does not mean he would not and could not do so. He is obviously skilled in thievery (he picks pockets and palms coins), he knows a little about picking locks (he tried to but has not picks with which to do so), he is so a keen liar, a great diplomat, and very athletic, thus showing a great array of skills which is still the halmark of the rogue.
I'd even say his shot on Barbosa in the first movie was a sneak attack, as it was a deftly aimed shot to a vital spot on someone who was not paying Jack any mind. I don't recall specifically, but the genre of fencing movies often has the 'hero' able to gracefully manuever his opponents into the position he wants them (as represented by the 4e rogue ability). I would think you can very easily model Jack Sparrow as a 4e rogue if there was no agility-based swashbuckler fighter strategy (at which point, he would be multiclass, because I don't see an non-rogue mix fitting his out-of-combat activities).
Another rogue example: the Prince from the Prince of Persia Sands of Time line of games, Two Thrones in particular.
He is obviously very athletic and strong judging from his climbing, running, and jumping abilities and how long he can hold himself up with just his arms. Very agile in his tumbling, balancing, and wall running, and fearless considering the places he ends up jumping from and to!
He is quite skilled with a dagger, though he can use one handed swords and maces. He sneak attacks opponents when he can creep up behind them or can get above them unnoticed (attacking while hanging from chains or jumping down from a balcony). He doesn't seem particularly strong in that it takes quite a few strikes to kill anything if he can't get the sneak attack off (at which point, it takes only a couple dagger stabs), but he uses the enviroment very well (jumping off of objects, enemies, or walls to attack). If he can catch his opponents off guard or off balance, particularly after using a strike that knocks his opponent prone, he can strike for addition damage (more sneak attacks if he manages Combat Advantage once combat starts).
He fights unarmored, his ability to parry or dodge an attack the only thing protecting him from his enemies' blades.
The Prince seems a pretty good archetype of a rogue striker to me. Decent in combat, but particularlly potent when he can get the drop on his enemy or somehow manage to force some advantage. He is athletic, quick, and daring. His own recklessness and drive to survive keeps getting him into and out of dangerous situations.
