This is more a problem of visuals presentation and taste, not because it's first person. See, some really old RPGs had even turn based first person combat, and it worked for its time. You have to ask your self one thing, would you enjoy it more, if every possibilty was visualy covered? If yes, than ask your self why, because what matters is if the mechanics are sound and if they work. Morrowind was far from a perfect game here, but it had more debth than any Bethesda game that followed it.
