Emblems should be tradeable.

We should be able to put these things on the AH. Running masses of the same content over and over again is pointless.

I'm well aware that grinding has always traditionally been part of playing an MMO, but that doesn't necessarily mean it has to be that way and I think Blizzard concur to some extent on this.

Buying emblems would enable you to raise the gold to do so in any way you liked, thus improving the amount of content enjoyed by all.
