The lord british thing.. a bit over the top from the dev's, rather funny though.
Blizzard have always been a bit heavy handed in the being serious and taking things too far department, they'll happily rip you a new one any time they feel like it if you don't play the game how they want you to.
The EULA is a bit of a scarey idea when you view it in this light, I've never really read it but i'm half expecting there to be new clauses come in that make you have to be white, straight, blond haired and a true believer in the fatherland's might. Heil!
Well.. maybe not.. but you wonder how far they would go with this EULA.
