1) What are the fundamental similarities among rogues/warriors/rangers?
2) Are there actually any real similarities among rogues/warriors/rangers? Is non-magic and physical adeptness/traits/attributes the closest things? I wouldn't say physical damage since rogues could be pure thieves that don't go into combat at all.
3) Are there any rogue/warrior/ranger subclasses that don't necessarily have to be physically trained? If we extend this to other genres, would hackers count as a rogue subclass?
4) Would physics also be a common factor? I mean rogues/warriors/rangers generally obey the laws of physics while magic doesn't right? What would be the mage equivalent in a scifi genre?
