Gathered motes have been account bound for around 6 months now, and these changes have had a negative effect on the economy and crafting progression. If the plan is to keep motes as account bound, then I suggest some changes be made to increase the yield of an individual's mote gain to balance the loss of purchasing motes from others.
Reduce the vendor mote charge from 12 silver 95 copper to 7 silver.
This will decrease the cost of a stack (7500) of motes from 971 gold to 525 gold
Allow medallions to be converted into COG coins in a 1 : 1 ratio
Add motes as a purchase option for COG coins in a 1 : 3 ratio
A stack (7500) of motes would cost 22,500 COG coins
Reduce the charter vendor charge for motes from 50 tokens to 15 tokens
This will decrease the cost of a stack (7500) of motes from a ridiculous 375,000 tokens to 112,000 tokens
Reduce the crown cost of motes from 675 motes for 30 crowns to 750 motes for 25 crowns.
This will decrease the cost of a stack (7500) of motes from 333 crowns to 250 crowns (I bet this will result in many more sales as well)
Increase the maximum gain of yorrick necklace to 35% increased chance from the current 26%
