Even with the most recent update allowing more of the Transmute Crystals to be stored in "bank" the limiting is rather silly. Having a limited amount able to be banked only makes it difficult to manage. They are very easy to earn and only have a very limited use. Make the amount to be banked unlimited as are Undaunted Keys, Tel Var Stones, and Alliance Points. Or maybe make them trade able or usable for purchasing items form the Undaunted and other specialty vendors.
Even with ESO+ I am starting to have to store the Geodes on my characters as my bank is full, and you cannot bank or store the Geodes anywhere but on the character that earned them.
