1. Do people even give a hoot about Class systems anymore or are you discouraged by them?
Yup, it increases replay value, of course adds tactical touch and it gives you flexibility/
2. If a game did have one would you prefer to be able to change classes at will or a "One choice and you’re stuck with it" system?
I'd rather have change at will instead.
Let me share this, Emil Chronicle Online has this gimmick of "one choice and you're there for life" for their base class, and later on, you can choose your 2nd job, but you can snag the other skill of the other 2nd Job class.
ex. Fencer -> Knight
Fencer -> Dark Stalker
You get 5 Knight Skills, then you job-changed to Dark Stalker and learned the rest of the Dark Stalker skills.
3. Exactly how should the Class system impact the game in your view, for example, like FFV where the story seems to revolve around it or more like an extra add-on?
In my game, it's more of a necessary add-on, and it will give my game a tactical touch.
4. Do you prefer classes to be restricted to what kinds of equipment they can use or do you prefer more freedom in that department?
That's a hard question... In my game, they're restricted to what kind of equipment they'll have, 'cause their skills depend on their gear! For instance, you wouldn't give a Samurai rapiers 'cuz of their customs, or... You may give a magician a handgun to protect him/herself, but not shotguns and rifles.
5. Should Class skills be learnt as you level up or acquired though other means? (Such as buying them with Points or the like)
I'd rather buy them with points, and even buy them with in-game cash (yeah, call it the in-game Cash Shop Skills, NetGame Crisis Saga has this coming!)
