To those saying that a 4e rogue makes a good swashbuckler:

What is it that makes it so? (I'm not being snippy - I'm genuinely curious). As far as I'm aware, the 4e rogue is a striker, which basically means dealer of lots of damage.

And that's about as far from my mental image of swashbuckler as it's possible to get without entering spell-slinger territory. If anything, I'd say that a swashbuckler is a defender, pure and simple. I can't for example, imagine a swashbuckler rushing through enemy lines to stab an enemy wizard, but I can totally see him interposing himself between a young lass and a horde of orcs, risking his life to protect her (or her life to protect him, in the case of a female swashbuckler protecting a young lad).

Is it entirely because the rogue wears little armor and uses a rapier?
