Ah yes, maybe 'false' is a bit extreme. I don't know whether they are sus-chords, or add-2, add-4 or some other chords, but I am reasonably simple when it comes to sounds and often find such chords a bit off, e.g. a chord like C-D-F sounds false to me because of the C-D. I suggest you use chords like those for the piano, and that is fine (keep doing it!) but it just isn't my cup of tea :)
Not so much criticism as personal preference, but I thought I'd elaborate!
