Take Thieves, all their skills, all their unique approaches to world, all the places where they can shine, all abandoned in favour of being more useful in combat and being made into another type of fighter.
I agree, rogues were an entirely dispensable class in P1.
These exceptions aside, however, class differentiation in Pillars was exceptionally good. They really do play differently, and your party composition dramatically affects the tactics at your disposal.
The thing with (A)D&D thieves is that outside a tabletop game, or a game specifically crafted for them, they kinda suck. They shine out of combat, and if a game doesn't have a lot of out-of-combat content, they're just deadweight. None of the party-based D&D computer games did.* Josh did the right thing by not cloning AD&D thieves in a game that didn't have the content to support them.
*Okay, partial exception for Storm of Zehir. That really did squeeze maximum mileage out of non-combat skills.
