So I recently read some blog about the new toy box (which is great) and the new reagent tab. But I don't grasp why they would add the reagent tab since I also have heard that they will be applying the 1-reagent-only-to-max-profession treatment (that Mining saw in MoP) to all other professions. They said that all in all there will be a "catch up method" of leveling a profession from skill level 1 to 625 by using the new (warlords of draenor) reagents just like miners can farm ghost iron ore from level 1.
Here's a pic given on that site: http://www.junkiesnation.com/wp-cont...agant-bank.jpg
And as you can see it's only old reagents sitting there that I'm guessing will have near to no value in WoD. At the moment I have about 2 alts banks/bags filled with cloth, another 3 with herbs and one has a guild bank filled with JC and enchanting reagents. Sure this is needed now, but if it is only for reagents in one expansion and not 5 then I just don't see the point. Why not just make the new mats introduced in WoD (ores, bars, cloth, gems, dust, gems, herbs etc.) stackable to high amounts (which they already have said they would do)? If the new stacks will be.. say limited to 200, then there's no point for a reagent bank unless you are stacking tens of thousands of reagents.
