Of course, it doesn't make sense that a multiclassed fighter/magic-user suddenly waive the restriction of armor vs. spellcasting magic spells.
What 3e did is a fair compromise, apply ASF when casting arcane magic spells. Even a single-class wizard can wear armor.
In 1e there were no restrictions on spellcasting in armor. Wizards didn't wear armor because they didn't learn it, not because it interfered with spellcasting. 2e imposed the restriction, who knows why. The 3e solution is a compromise, but horribly poorly thought out and difficult to justify in campaign terms.
Somatic components require the caster have one arm to gesture freely. OK. "Can I get a breastplate w/ no arms? Yes, but you still have ASF. Can I carry a shield in the other hand? Yes, but you still have ASF. What about elven chainmail? Yes, but you still have ASF. Why? Because wizards shouldn't wear armor, it just ain't done. At least if they said that wizards had to perform ballet to pull off a spell with somatic components, that would be something!
And don't even get me started on the Concentration rules. You get a roll to pull off a spell when you're balancing on a ship's yardarm during a storm, but there is no skill in the world that will make you better at performing the gestures with a heavy leather sleeve on your arm. Or a bare arm, and a layer of leather on your chest.
Bah. Sorry for the rant. Back to multiclassing:
To emulate the old system, you're going to have to agree to split your XP earning toward the classes you have. For simplicity's sake, use the XP level progression for each class. You want to earn XPs rapidly as you did in 1e? Start rewarding 1GP=1XP.
Believe it or not, this would actually work fine. Give them the best HD of the two, best skill points, all class abilities and class skills, and the best saves. You end up with a gestalt character with lower HD, saves, and BAB than the rest of the party
but more class abilities. Does this sound unbalanced to you?
XP: Normal levels: Multiclassed levels
1000 2 1/1
3000 3 2/2
6000 4 3/3
10000 5 3/3
15000 6 4/4
21000 7 5/5
28000 8 5/5
36000 9 6/6
and so on...
So while the other characters are 9th level, one of their companions, the fighter/wizard, has 6d10 hp, +6/+1 BAB, +5/+2/+5 saves but also 4 fighter
bonus feats and can cast up to 3rd level spells. Not so different from a
fighter 4/wizard 5, you might say, but at 20th level the standard multiclasser
is 10/10 and this version is 13/13.
