If you don’t want to make them roster bound (for some reasons), at least please place the harmony (and other) shards in a special section of the currencies window that explicitly says it’s character bound. Right now, it’s not, and it’s just right in the middle of other currencies that are roster bound.
Now I have 300k harmony shards on a character that doesn’t need them anymore, and starving on the second because I didn’t know. Bad UX design.
Of course, the best way would be to fix that and make harmony (and other) shards roster bound instead of character bound. Why are other components required for honing shareable but not this specific one?
