Ok then, so I'm going to trial the Level Up version of Expertise in my next game, where you add +1d4 instead of double proficiency bonus and give all the players an expertise related to their background. The idea, I think is that as it is less powerful and more random, the gap between haves and have nots is not as wide, and you can dish it out to other classes so they get good at their core skills too (like fighters with low charisma being terrible at intimidation), but there are ways to stack it in Level up that don't exist in 5e, so I wonder how this will affect rogues using their core skills.It is pretty weird that these tangents so rarely end up talking about something interesting and rather some point of agonizing minutia isn't it? You'd think we'd rabbit off talking about cool stuff more often.
I suppose if opening locks and disabling traps is now Sleight of Hand, and thieves tools give advantage on every check, might it be sensible to reign it in a bit more?
