As intell and Golnei mention, he's kinda empty as he's meant to be the 'everyman' shell for the player to occupy while his supporting cast are overall awesome and memorable.
This leads to the issue where if we're going to get a rep from Xenoblade it's unfortunately going to 'have' to be the least interesting character you can actually play
It's the same issue we'd hit with paper mario (amazing characters but we'd end up being gated with yet another silent protagonist AND a mario before we get to the good stuff) and to some degree even Chrom (FE has a super diverse cast yet we apparently need to burrow through yet another blue-haired male lord before we're 'allowed' any of them... if ever

I'm not going to call Chrom a swordsman because my brain can't accept Samurai would go for a triple dupe by introducing this character )
