Yeah.. I really wouldn't grind up pets JUST for this. In fact I wouldn't suggest any change in habits at all. It just means if you HAPPEN to be doing this, because you like it, you might have a few less dailys to do each week.
For me, it means I can spend more time doing something I like (pet battles), and less time doing something I don't (dailies) for the same reward. I don't have time for both.
