The few “Undead Paladins” that have existed were all brief appearances, and all directly broke the bounds of the Lore itself.
I get what you’re getting at, that religious zealots are sometimes totally willing to go to crazy extremes, but the “lighting yourself on fire for your faith” is the kind of sacrifice you make once. And there wouldn’t be any chance of survival, as the Light being infused in their body would destroy it completely.
Because if it didn’t, then Blizzard would suddenly and dramatically be changing what a “Paladin” is entirely.
That’s very much the kind of concerns I have about just opening up everything to everyone. There are a lot of combinations that just DO NOT work, and to MAKE them work, it would mean Blizzard altering the very identity of either the Race or the Class, or both.
And again, it just further waters-down the cultural aspects of the races as well.
In the real world, yes, “anyone can learn to do anything”. Anyone can pick up a blacksmith’s hammer, or a mining pick, or what have you. But that is a far cry from saying anyone, from any cultural, could have a deeply-embedded, unshakable belief in the Elemental spirits, communing with their ancestors to craft totems to further deepen that connection.
If Classes are just all boiled down to game mechanics, simply because “well I don’t care about the Lore, I just want to be a Gnome Druid” and things like that, I think WOW as a whole suffers greatly.
Like I said, introduce more “Allied Races” to fill in the gaps if people really feel like there should be more options. Eredar that are attempting to mend the rift between them and the Draenei, perhaps Gnolls (the revamped ones look pretty great, although a little too “lean” and less cute than the Vanilla ones), things like that.
While I certainly respect player creativity, there IS a hard line between “player creativity” and “meaningful world-building”. Otherwise, you would have characters like “my character’s parents were killed by Orcs, but they found him as an infact and decided to raise him, so my character is a Human Shaman that fights for the Horde”.
Rules exist to make the game world feel BELIEVABLE and ALIVE. Hell, even JK Rowling mentions the importance of “magic” having certain rules in the Harry Potter universe (even if she didn’t seem to establish what those rules really were).
This is why people often talk about D&D, but virtually nobody talks about the “world(s)” they inhabit in D&D, because the worlds and settings themselves are largely meaningless, they’re just a sandbox for players to do things in. WoW has (or at least had) a deep, rich world with a lot of history. Throwing all that away, simply because SOME players don’t like restrictions, is a failure of game design, and an admission that none of the Lore matters anymore.
