Pretty sure most or at least many English VA are also aspiring actors/singers. At least most of the ones I've looked into have their own webpages with professional headshots, voice demos, etc. A lot of them actually do end up getting minor parts in a variety of shows, movies, etc. I don't necessarily think they're less professional. Usually if you don't like the voice acting, it's because of casting/directing. As I understand it, dubbing studios usually have the VA knock out their lines very quickly, and it's on the director to decide when they've got a good take, and to guide the tone, emotion, etc. The VA themselves frequently don't get to watch the show or get a point of reference from the original acting (but the JP VA don't get that either).
Ok, now we're going to get slash fiction of Wint x Kachi somehere... rule 34 and all...
Never confuse your inference as the listener for an implication of the speaker.
Good games are subjective like good food is subjective. You're not going to seriously tell me that there's not a psychological basis for why pizza is great and lutefisk is revolting. The thing about subjectivity is that, as subjects go, humans actually have a great deal in common.
