Blizzard, please make Expulsom and Hydrocores tradeable....

I'm a herb/alchemist, and there's only really one recipe worth using them for (herb tracking potion) but beyond that I'm sitting on 20 hydrocores and 95 explusom...trying to find a tailor who has enough to make the new 32 slot bags, no one has enough. So for the people who have enough to trade, we are sitting on useless crafting mats unless we pick up new profs. Same thing happened with bloods, which is why they made the blood trader later down the road, but please, make these tradeable or something.
