This may be a bit radical.

I was thinking that it would be cool if a MMORPG had a random feature that would make a character become, a Dragon, or a hero or something.
What I mean is, About 5% of the time after someone creates a character, the computer runs the algorithm and they either get into the game as the character they selected... or they appear in a high mountain area as a giant and incredibly cool monster of awing strength. Or if they are a hero, they appear as their character with special and awing skills that no one else has in the game.
Then they can then either terrorize the land (pillage and burn villages..etc.) ... or help the land. They should be really, really hard to kill, so that only another hero can kill them or a lot of people together. So that way it forces Human interaction and creates a sense of camaraderie.
Also they * the aggressive heros and dragons*should drop a lot of goodies like a NPC animal so that they are way worth killing even in a large group.
The only catch to being born a Dragon/ hero is that once you die your character is dead, and you regen as the character you chose (or just have to make it over again)
I figure that since this game is free.. that mebbe the idea could be at least tested.
Let me know what you think!
