I like the idea of a Runemaster. They could be a very unique class. There is nothing preventing a stat conversion on cloth gear. The class could work because Blizzard are clever like that.
However, it is just a pipe dream. I am of the same sentiment as others: DKs took hell to balance. An 11th class would just be a nightmare - in so many ways. :/
But hey, at least we would have a greater chance of getting that extra character slot!!

I'm sorry, I just have to address this.
Blademaster: like a warrior, only... different.
Demon Hunter: It's a hunter. But it uses shadow powers to boost its attacks. But it's like a hunter.
Ok, so those are both classes that are far too similar to existing classes in the game. Even closer to other classes than paladins are to DKS. Runemasters would be very unique in terms of gameplay. Not only would the rune system not resemble the current iteration of the DK rune system - in any way, shape or form - but to have a monk-type class in the game would in itself be new, exciting and something that hasn't been done before. Even a cross between a Brewmaster and a Runemaster would be pretty damn unique and amazing.
I just hope that if another hero class is introduced in the future, that they will be much better at balancing and integrating it into the game without affecting everything around it for two years... >.<
