Definitely understandable. The FFIV logo strikes me as particularly poignant because of what happens to Kain during the story. Meanwhile FFI's seems to be more "hey, he's got a sword! AWESOME!" which is appropriate for FFI considering your party never even got dialogue, but as the series evolved it began to take on a new face. FFIII was more a return to FFI so perhaps generic hero to illustrate genre isn't such a bad thing, but I really do see where you're coming from.
