You're making a whole lot of assumptions based on 1e and other post OD&D rules.
FireLance said:
1. A magic users cannot cast spells in armor.
According to a literal reading of the rules, M-U's can't cast spells in magic armor.
Pg 6 of M&M: "The whole plethora of enchanted items lies at the magic-users beck and call, save the arms and armor of the fighters"
Pg 8 of M&M: "[Elves] may use magic armor and still act as Magic-Users."
2. A pure-classed cleric of a god of hunting cannot use bows.
Like the language in the magic-user section, a literal reading of the rules states that clerics cannot use magic arrows:
Page 7 of M&M: "Clerics gain some of the advantages from both of the other two classes
I Fighting-Men and Magic-Users) in that they have the use of magic armor and all
non-edged magic weapons (no arrows!)..."
Compare that to the strict prohibition on everything other than daggers for m-u's on page 6 of M&M: "Magic-Users may arm themselves with daggers only."
3. Dwarves can't be wizards, elves can't be paladins, or dwarves and elves were classes, not races.
There weren't paladins in the original rules. Dwarves and elves weren't classes. The "race as class" thing happened later.
4. Humans can't multiclass. Demihumans can't dual class.
There weren't any multi-classing rules. The ability to switch from m-u to f-m and back was special ability distinct to elves.
5. A gnome could be a fighter/cleric, a fighter/thief or a cleric/thief, but not a fighter/cleric/thief.
Gnomes weren't player characters, they were monsters. The thief wasn't in the original rules.
6. A human fighter with Strength 14 and Intelligence 18 cannot dual-class to wizard because he is not strong enough.
Wrong. From page 10 of M&M: "In order for men to change class they must have a score of 16 or better in the prime requisite (see below) of the class they wish to change to, and this score must be unmodified." The fighting-man in the above example could therefore become a magic-user.
7. Some magic items could only be used by members of specific classes (certain wands and staves could only be used by wizards, for example).
True enough. Show me an edition of D&D where this isn't the case. Are fighters reading magic scrolls in 3e? Paladins using Staves of Wizardry?
8. A ring of protection does not provide a bonus to AC when used with magic armor. A cloak of protection does not provide a bonus to AC when used with any armor except leather. (I may have remembered this incorrectly. Is so, could someone post the correct version?)
I don't know where to begin on this one. Magical armor and Rings of Protection don't change one's AC. They effect the attacker's hit roll. Further, there is no language whatsoever regarding "stacking" these bonuses. I've never heard of anything like that rule
Really, most of your concerns regarding players getting the characters they want is handled in this passage from page 8 of M&M:
Other Character Types: There is no reason that players cannot be allowed to play as virtually anything, provided they begin relatively weak and work up to the top, i.e., a player wishing to be a Dragon would have to begin as let us say, a "young" one and progress upwards in the usual manner, steps being predetermined by the campaign referee.
The six player types in the original box were to be considered a starting point. The product history of OD&D, beginning with the very first publication of The Strategic Review, which introduced the Ranger, is replete with examples of DMs creating new classes, races, and character types. Check out the wierd stuff in the Arduin Grimoires, for example.
You're perfectly free to dislike OD&D. I know it's not to everybody's taste. But you should really crack the book open before you start dissing it.
