OK, this will never happen, but people talking about how they woudl love to change classes reminded me of some old talk back when level cap was 65. People talked about multiclassing basically having a second class.
So if they ever allowed multiclassing and you could pick a second class and get all of the abilities of that class as well as keep your own, what would you pick.
As a monk I would take Paladin for healing, plate armor, fearless, and slay.
