They sound fine to me in ItN.
And I'll say it again, your Nefarious is amazing!
And Qwark as well. I keep complaining about Clank, but overall our dub for A4O was really great. Ratchet, Neffy, Qwark, Cronk, Zephyr, The Plumber, Spog, Dinkles, Kip Darling… They all had perfect voices. Unfortunately, they didn't do quite as good with ItN. Fans kept complaining about the dub and SONY decided to change the duo's actors. And it didn't work well. As I said, they voices theoritically are better matched, but for some reason they get pretty annoying very fast. Well, Ratchet is not that bad, but the ItN Clank for some reason annoys me even more than the old one. I think it's something about the way this actor talks in this particular role, since he never annoyed me as any other character. I also didn't quite like Neftin in there and Zephyr is just a… Man, I am missing words for this. Luckily, side characters (and f***in' awesome Vendra) are still very good.
