Rogue (well, Thief, but Yoshi-P thought that had too many negative connotations for our good-aligned WoL) turned into Ninja in the original Final Fantasy, so it makes perfect sense, in terms of Final Fantasy. Totally makes sense that people would've wanted a more straight melee role, though. I am glad that Viper is coming out for folks that wanted more hacky-slashy then boomy-bangy.
