From the games descriptions the two are quite similar in spirit. In application the two are very different of course. The Blade has magic, the Swashbuckler more thief skills etc.
Which do you prefer? Have you played both? Obviously someone who has played both is better able to give an acurate comparison, but I'd be interested in hearing opinions.
Do you see the two as kindred spirits?
Does Mazzy's portrait look like she should be a sexy female Blade?
Is a Swashbuckler really a pirate, and if so, why doesn't it have a CUTLASS proficiency..... har har....me hearties......
