Stackable soul shards only solves the problem of storage space... which isn't a problem to intelligent organised people... If soul shards need changing it's to make them more functional and more fun to use, not to give you more space to carry loot, Blizz seem to have the right idea.

The biggest problem with soul shards is for the builds that burn through them quickly, destro, etc. The problem is that they tend to run out of the shards and that they hate farming masses all the time, having the shards stack, of course, would not even begin to resolve that. Even if the stack was 100 large they'd still run out and still need to farm, the only difference would be infrequency and they'd have to farm for even longer.

I'll never understand why the lazy disorganised masses who want a major gameplay change for the sake of carrying a few extra stacks of frostweave cloth or grey named loot or whatever have the loudest voice.

@Continuum6 - You find your pet bar THAT hard to use that you had to have such a huge tantrum?
I always command my pet via the keyboard just like i do with my own abilities... Why don't you just re-bind the buttons?
Alternatively have you considered the fact that you just prefer the Rogue and Drood and that is enough? Why do you also have to enjoy the Lock? My first toon was a hunter, sometimes i go back but i happily admit it's my second toon i enjoy the most.
The Q&A was disapointing because Everything, bar the flying mount, is either obvious design principles or has been mentioned before, even the green fire... but still, it's more than we've had before and hardly worth throwing ALL the toys out of the pram eh?
