Having well known archetypes isn't a bad thing at all, it what's what you do with them. What are they beyond 'witty cool guy' and 'happy go lucky girl'? What situations do they get into? What about their dialogue? You can make any kind of character work if you know what you're doing. At the same time trying to avoid common tropes for the sake of trying to avoid them will probably not work out well.
You're right there. It worked for FF10 (while it didn't for FF8 and FF13), so maybe it just really depends on the person responsible in how some character is presented.
Or in some instances it's just done better. But hey, opinions. The magical word that makes saying Superman 64 is the best game ever not stupid.
