Multiclassing in 2E was a lot more forgiving. You had a choice between ugly and horrible math and ugly and horrible game design, and 2E’s unforgivably clunky race restrictions limited implementation substantially, but you’d natively end up with a lot more class levels for a given XP total, such that you’d usually be out one or two levels in both classes, or in your highest class if you were dual-classing. There’s a lot you could do with that, especially if you were working with the thief’s percentage-based skill set.
