Steeliest of the dragons
Well, that's where you-as-DM need to pull out the kitbash tools and rethink said restrictions. I did, a long time ago, and came up with this (original limits in brackets where-if I remember them):
Rangers [must be G] can be any
Cavaliers [not sure] must have a good or lawful component
Bards [must have a N component] can be any
Monks [must be L] must be lawful
Thieves [cannot be LG] cannot be good (in play, this is slowly weakening)
Druids [must be N] can be any as determined by deity followed (they are "Nature Clerics" here)
Assassins [not sure, it varied] must be evil
Necromancers [new class] cannot be good
Paladins [must be LG] must be lawful good
Lan-"chaotic-something, depending on my mood"-efan
Great list [MENTION=29398]Lanefan[/MENTION].
Here's my game's alignment "restrictions" if you want to call them that...they're not "bugs" they're "FEATURES"! lol. Anywho...
Fighters: Any
Barbarians: [must be chaotic] Must be Non-Lawful. (But Barbarians in my game are also solely human tribes of a certain region.)
Rangers: [must be Good] Must be Chaotic ("Bad" guys can know the wilderness and conduct guerilla warfare as easily as "Good" guys.).
Paladins: [must be Lawful Good] Must be Lawful Good (or Lawful Evil, anti-paladins do exist. But since I am not inclined to run "evil" campaigns, the PCs are more likely to encounter one than be one.)
Clerics: Any
Druid: [must be True Neutral] Must be True Neutral only! (members of a world-wide organization from time immemorial here)
Shamans: [homebrewed class] Must be some Neutral (NG, NE, LN, CN or TN) depending on society they coming from.
Mages: Any
Specialist mages: Any, though trends for certain schools apply. Necromancers are almost solely Lawful and/or Evil, though they are restricted to being "non-Good." Diviners are almost solely bound to Neutrality (though a particularly "righteous" or "diabolical" individual slips in there from time to time)...for example.
Thieves: [any non-good] Any non-Lawful. (Even evil creatures don't like their stuff being stolen. You've gotta "break the law" to steal stuff.)
Assassins: [must be evil]: Any non-lawful and non-good. (a faltering bishop of an LG deity could, if he so chose, hire a Neutral or CN assassin...not wanting to associate with blatantly evil persons...for his own nefarious plots...or an assassin seeking to redeem his immortal soul might offer his 'talents' to a "good" church/person/cause.)
Acrobats: same as Thieves, any non-Lawful.
Monks: [must be lawful] Must be Lawful.
Psionicists ("Initiates of the Emerald Tear" in my world): very rare, but any alignment is possible...though Neutrality does overwhelm the Order.
