I think when it comes to artlangs, a lot of stuff really can be justified with "Because I like it that way." (Why do you have ten vowel sounds? Because I felt like using umlauts this time around. Why do all your verbs end in a vowel? Easy agglutination pronunciation, baby!) I mean, there's almost always some kind of precedent in real languages. They're so weird!

...that said, I'm still a little bitter that when I outright asked for commentary on a few specific linguistic choices, what I got was critique of my web design. Ah, internets.
