Nope. Would just encourage grinding and leveling pokemon so that you never fight unless your poke's are 20 levels higher than your opponents.
In FE you play a limited number of battles and they play out a little like chess, whereas in pokemon you fight hundreds of battles and fainting is an unavoidable part of any fun battle. --- "We were going to a funeral, but it looks like we got buried." -J.R. Smith PSN: Whsguy
