So with the addition of both "expertise" and Gnomes I decided I wanted to do a little test. I picked a Deep Gnome Rogue (+7 on Stealth Check AND Advantage) and moved to the first ennemies of the game with the Imps with Laezel (+1 on Stealth Checks AND Disavatage due to armor) And they have the exact same cone of vision.. I seem to recall in DOS2 the more sneak you had the smaller those cone of vision would become.

Now I know this is not DOS2 but it feels to me that you can be as sneaky as a rogue made for stealth as a clumsy 10 Dex Fighter with Plate Armor.. from what I gathered theyre is no dialogue sneak check as of now.. the only time you "Roll" a sneak check is if you go inside a person's cone of vision passed a certain distance otherwise if your too close they just spot you instantly with no rolls. Or When you try and remain hidden with an attack from stealth.

As of right now its more efficient to sneak around to either use invisibility...use something that removes vision like a Fog Clould in wich case anyone can sneak..or just find a path around via stuff like either jump or misty step.

The Stealth skill feels completely pointless as of now and I find ridiculous I would much rather invest on skills like knowledge skills or perception/insight for a rogue then bother with the sneak skill since those can be used to succeed at pretty important passive checks.
