True rarity of the Minipet Ghostly Hero

hello there,
earlier today a thought struck me: how rare is actually the minipet ghostly hero?
i've seen gaile say around 20 drop each year or so, but i am not sure if that number was confirmed.

does anybody know how many of these drop / year from the chest awarded to the winning team in hall of heroes? any guesses? any real facts?

Well, I think 20 each year sounds close to the truth. I only know 2 players who got a ghostly hero from halls chest, one is in [be] guild (got the hero like a week after it was implemented in the game) and the other in a less famous french-speaking guild (dropped it 1 or 2 months ago, sold for 600e). Some other people must have dropped it from halls of course, but those 2 are the only ones I know.

i have seen maybe a dozen or so for sale since is dropped. they could however, be a few just being resold over and over.

i do however, remember talk of a limited amount dropping per year.

With all this duping that happened recently the amount of Ghostly Heroes are probably even less now. Makes me sad to see alot of them going down with the people that paid tons for them - and just disappearing from the game.
Hopefully ANet will compensate the loss with some few more drops from HoH chest?

would be nice if Anet could give us some sort of report about how many of the limited edition (very rare) pets are in circulation. IE...on un banned accounts
