Here is the problem with Mousse's argument and the reason that DM's need firm rules for organized play.
His first statement:
Given the generally evil nature of bringing undead into the world I wouldn't allow it at my table. No matter what Mr. Frost said.
He doesn't care what the ruling is, he cares what he thinks. It is also the reason that he states later:
I think what's being missed here is that if a player has a problem with the table they're at the most powerful statement that can be made is to walk away. I've done it, and encourage anyone that finds themselves seated at a table they're truly unsatisfied with to do the same. Trust me, if it happens more than once the GM usually doesn't continue.
Josh has already stated:
If your PC wants to raise some skeletons and their alignment and deity are okay with that (animated dead is an evil spell, after all) then they should be allowed to.
and
Yes, you can use animate dead so long as your alignment and deity are okay with that.
In fact, the final rules might have necromancy sorcerers and wizards that are playable. One power in the BETA allows the summoning of undead to serve them in a potentially playable class.
The key problem is DM's that allow EGO to guide their decisions rather than rules.
Personally, I don't like the whole Cheliax thing and hated one of the missions in a module I ran at convention. It involved six innocents dying to fulfill a mission. It only encouraged childish play and glorified evil in my opinion.
The key was that I understood that these were the rules of the game. I was not a lord and master, but a caretaker that was there to promote and run the game as written. Not my vision, but to run an organized play scenario.
Home game: does as you will
Convention for organized play: Put your ego aside and let the players work within the overall framework. Realize that this game needs mature DMing and structure to grow and survive. It needs to allow different types of play.
Remember that someone created their character to have certain tricks or to represent a vision of their idea of fun. They read the rules, the built and played the character within them. Don't take that away when it is legal, because it doesn't suit your vision of the character.
You don't need a heavy hand Mousse. The player characters will likely destroy the thing as Josh suggested. The fact that they can, has already inspired the player in my home group (after Josh's ruling) to stop heading down his current path and take his next level in Bard.
