Cimorene

I was just catching up on my flist, and I was so happy to find that someone feels the same way I do about epithets. For awhile, of course, I used them quite liberally, so I'm as guilty as anyone. HOWEVER, as soon as I realized that I disliked reading them in other people's works, I stopped using them. Some words can be repetitious. Characters' names are not. Use them.

Which brings me to the actual point of this comment, a moral question: when I am beta-reading for someone else, is it appropriate to mention that they might overuse epithets? I've encountered this several times. I was worried that it might be a simple matter of opinion, but now I wonder if I should say something. I'm just curious to know what you think. XD Advice, please?
