I adore first person dungeon crawlers, they're probably my favorite subgenre of RPGs. I found Class of Heroes boring and, no matter how hard I tried, couldn't spend more than 10 hours with it. I can't say I'm all that interested unless they made some changes to the formula.
That said, I think this type of thing is an understandable idea. Localization of these games is a niche within a niche. To reduce the risk, let those who are willing to assist do so. Now if this was for a larger game and a larger company? Absolutely not.
