One painful thing about being an altoholic is that I also feel compelled to research everything on all my characters. This means my bank space (maxed) is constantly full with things to research.
This will of course reduce over time and you can delete something and just make a new one of that type when you need it, but that requires tracking what you have researched outside the game (such as on a tablet app, great tool, but a pain to keep updated) and it also requires swapping characters to craft an item you need to research, something that is quite time consuming, even if everyone is sitting in the crafting area in Alinor (for example).
How about adding some knowledge of what my other characters have learned. Then allow me to research any trait as long as that trait is known by another one of my characters? You could take out a trait material and enough mats to craft it (level 1 would be ideal for me, but I could live with my current level or even max level) so that way it would do the same as me jumping on the other character, crafting the item, putting it in my bank and then jumping back.
A related item would be to also know which traits have been researched on another character and possibly which character(s) it is. This would keep you from deconstructing something you really need.
I know this is only a temporary problem until everyone learns everything, but that is a fair ways down the road. The pain in this hits newer players more, which is not a good thing if you want them to be happy with the game.
Keep in mind that you would still need to do the research, it would just easy making items to research as long as someone in your character group knew how to make that item with the desired trait.
Yeah, I won't hold my breath waiting for this, but it would be nice.
