Q:
Rainbow Jellyfish Remodeling
The harm would be having a completely unique pet only available to GW1 players, which Anet doesn’t want to do. They only want cosmetic skins for GW1 players, not anything that would give an inherent advantage to them over other players who never played the original.
Unless it was just a reskinned Hawk or something as opposed to an actual unique pet. Never played GW1 so I can’t say how feasible that would be or if it would also be “an insult”. Though there’s already a reskinned HoM bird, so having 2 might be a bit much even if it was feasible.
