[@Excal] You got the basic ideas, I'd just like to add in a few extra details. 

Crasher/Launchers specialize in high-powered technology. But not 'Advanced'. This usually ends up with big weapons, lower end power armor, etc. So yeah, they're weapon specialists. But they are often tanks too.

Artificers/Collectors - yeah pretty much. 

Ciphers - Yeah, this is a good way of putting it. Technically, anyone having enough knowledge of Hieracon can use :links, so it makes sense these people can too. But because of their mutation, they have to carry less to avoid detection. Did I put that in there? I'll check later.

Techs - I see them in as more technical and practical, in terms of machinery at least, than Artificers/Collectors. Because they usually have some form of modded body replacement, they are not as restricted to cool downs. Obviously, they don't have the vast amount of options that :links provide, as a result. 

I added in a new class recently the 'Mechanic' - Basically a cross between a techy and a crasher/launcher, who handles robots. Pretty simple.
