Being optional means I can ignore them. I do plan on playing with other people though and that could lead to an issue. I will be sure to bring it up before I start a game with my friends.

An option to "lock" Characters from being re-rolled and manipulated would be nice. Just give me an option to turn it off as host of my game.

You cannot allow multi-class characters to progress through spell levels at the same pace as single class characters, that is silly. Why wouldn't everyone grab a spell class then. One level of Cleric can buff and heal. And continue to progress through the spell levels?!
