Let's say you're a Ftr/M-U. Your level 2 Ftr is around ~2000, and your level M-U is ~2300. Those numbers are probably way off. You divide the XP evenly between them, thus they may level at different times. The advantage of this is that you generally only lag a couple levels behind in either track vs a single-classed character. Balance-wise, this works out better than in 3E, where a level-6 Fighter/Wizard alternating levels is only effectively a level 3 wizard. This disparity is exacerbated the higher up in level you go.How did the 1e style work again? I can't remember.
Well, AD&D-style works out better for casters (especially since up to name level, AD&D experience tables were pretty much exponential), or part-casters; in 3.x, anything that caused you to sacrifice caster or manifester levels was a really bad idea due to artifacts of the magic system. But 3e-style worked decently for non-casters (to the extent that non-casters weren't gimped). Still, AD&D style multiclassing (or 4e style dabbling with feats or full-on hybrids) generally worked better.Let's say you're a Ftr/M-U. Your level 2 Ftr is around ~2000, and your level M-U is ~2300.

Ugh, anything but 3e. That just led to all sorts of frankensteins and many ultra specific PRC's that just diluted content, unless you are truly multiclassing like need to keep within 1 level of each other in a hard rule.
Oh, to be sure. My main concern was hybridization of non-synergistic character types, which is my primary area of interest with respect to multi-classing.But 3e-style worked decently for non-casters (to the extent that non-casters weren't gimped).
