Ok. i finally got the nerve up to load Ez hero v3.3. 1.)how does this work?  2.) how does it affect the characters in game?   3.)will it change the characters already loaded.  i know this is a old news topic but i shy away from stuff i dont understand so be gentle when you read this and say "WHAT???". thanks to anyone who helps explain this. Hey, i'm an old guy. what can i say.
