I am on my elementalist right now, looking at the tokens my warrior got before the patch.
Can’t drag them into my inventory, even though it says “account bound” in the tooltip.

We will be making pre-patch tokens account bound in the next patch. That will probably be is less than a week. Hold onto your old tokens they will automatically update. This will also fix old Obsidian Shards.
