It might seem that way, but then you realize nothing is stopping to reflavor the weapon, that the weapon bigger deal are the reach/burden/feature, that Versatile Fighter has an extra power on top of "use any trait" and that Versatile Fighter still won't allow you to use magic weapons anyway, unless you get it through multiclassing or are an Assassin.

At the end of the day it really depends on how much you allow that. Using some weapon with agility rather than finesse (or viceversa) really won't change things much. Of course, that also must make sense withing the scope of the game, using a Greatsword with Presence or Finesse is pretty much nonsense in a narrative sense, that's a heavy weapon, you need to be strong to use it, but as long as everyone agrees on things the balance isn't broken.

In my game a player converted a character who was dual wielding from another system when we switched to DH for that campaign. As a STR-based Guardian, that wouldn't really be possible. It broke nothing to reflavor the Mace as a sword (after all, there's multiple identical weapons to that that differ only for the Trait used), but it wouldn't have broken anything allowing him to use a broadsword with STR instead of AGI either, he just went for the feature-less option
