I think it's fine and well that everyone can do Sleight of Hand and Stealth, it's good design. But as a primary rogue player, I really, really want them to give us the Expertise that we rightfully deserve, so we can at least be a little BETTER at those things (or whichever skills we choose) than all the pretenders.
That would be fine and actually I don't get why the expertise feature is missing.
Even currently, astarion fails a lot on disarming traps, so expertise would be a good addition.
