Honestly, I can't fathom why Dodge isn't already in. As far as Ready, I'd be fine with just readying an attack or cantrip when an appropriate target presented itself. It would need to be added to the Reaction System, ideally. Otherwise, the casual player wouldn't know it would expend their reaction. I suppose the casual player also wouldn't know readying a spell would break concentration either though, but I don't know how they'd implement it in the end.
