I don't think that being able to develop in multiple languages implies that you're going to be bad at developing in those languages at all.
I've been a dev for a very long time, and am competent in a lot of different languages (expert in far fewer, of course). But I don't use all of those languages all the time. I use the one(s) that are relevant to whatever my current project is. That's usually just one or two at a time.
