Gem Purchase Refund?
The upgrade does have legacy armor and so the people with the normal DD edition don’t feel left out, that armor is also sold in the gem store.
But you’ll have to wait for support to answer you. It’s kinda frowned upon to create a ticket and post on the forum right after.
Hall of Monuments armor is Heritage armor, not Legacy armor. The Heroic Edition does contain Legacy armor, just as it states. In order to obtain Heritage armor (HoM armor), you need to add achievements to your Hall of Monuments in GW1.
You may or may not get a refund; you can only find out by contacting Customer Support, and waiting for their response.
