If and when I know enough about Hiei I'll get back to you on that. I'm going to assume stats can start (at level 1) at no more than 18, and assume a minimum of "+X" magic items (that is, belts of +6 to Strength). First have to know what I'm trying to write up, which will take a while, so paitence is a virtue.
Personally, I don't mind character variety, but I think any reasonably coherent character archetype shoudl be one that can be played as a single class.
"Boolean: Yes! Yes, multiclassing as a concept is deeply stupid, and has always been stupid, and will always be stupid. The entire fucking point of having classes is to say that somebody who is a Monk is not a Druid and vice versa.
That doesn't rule out any particular *concept*. Because we aren't tied down to the D&D classes. So we can totally have "Dawnwarden" be a class, for members of a holy order who run around stabbing fools with gilded swords, firing lazer beams and Summoning demons. Or whatever. The Spells and sword character lives on. But he should probably run around in gilded armor covered in arcane symbols. And even if he's under cover, the minute some guy whips out a sword and starts lasering, you should know that's a Dawnwarden. And if he starts animating vines or tunring into a snake, you can and should call bullshit, because Dawnwardens don't do that , Fangthanes do."
So you can play whatever you want...but not everything you want in one character. That is made of fail. Wanting to be Inigo instead of Gawain instead of Beowulf instead of Gilgamesh is not. Wanting to be Gawain and Inigo winds up with ludicrious characters.
As for option variety:
Here, let me grab the quote from Frank:
FrankTrollman: Swinging a sword is NOT A PROTECTED ROLE! It's not even interesting. "Using Magic" is far too fucking broad to count as a protectable role as well. The Kach? Tenshin Amaguriken is a protected technique. The Dragon Slave could be a protected technique.
That's what I mean by "Sword Guy". Being a "Sword Guy" means you get techniques that no one not a Sword Guy can get.
Whether the ideal basis for the Sword Guy class is something like the Fighter (almost certainly not) or warblade is another story.
So, a character shouldn't need multiclassing if all of his abilities are part of the "I'm a samurai" shtick.
Now, that would require rewritten classes. But honestly, the game could use those anyway.
That quote clear it up? Because I don't think we really have that big a difference in terms of what archetypes we want to be available beyond "I don't want a setting with ____.", which is purely setting.
