I was thinking that regardless of how you feel about bans, having a cool animation like Dhuum in GW1 would be a neat little feature. Dhuum doesn’t seem to be around anymore in GW2 lore, so something more fitting would have to be thought up.
My idea would be to have a small-ish dragon champion pop-up, imprison the character in a crystal (possibly ice or obsidian depending on the dragon it’s aligned with) and then proceeds to fly off with the crystal, the character screaming out it’s “falling to death” scream."
