This happened to me recently. I've started focusing a lot more on an alt than on my main, partially because I'm not 100% sure where I want to go with my main, and the alt right now is a lot more 'focused.'
As Melkire said, I don't know why that would be a faux pas, unless you're leaving other people hanging. So long as that isn't the case, why would concentrating on an alt be a bad thing?
