Monster math, and the way the prof bonus is baked into things, should be the relatively straightforward part.
Its always the PCs and their damage were it gets hairy. 5e seems to assume a lot of rounds of combat per day, to get PC damage to average out.
Not sure how this interfaces with the monster math, but it must!
I thought I saw a post somewhere, that the Monster damage, is related to encounters per day, and the PC Hit Points, not damage?
