I have only seen one, and as is very, VERY common on these here forums, there is always 10+ threads all complaining abut the promo, and how it's gonna "kill the market"
Most of them come from F2P players (Not that I hate f2pers, it's just they're always teh one to complain, for some reason), and I, a paying player with the 800/month limit (I'll admit to it, blame the explorer pack promo :P) decided I'd share how I feel about it.
Honestly, I don't care. Everyone is prolly gonna comment like "OMFG ur that guy with three of those y u r complainz rich boy!" I paid 2.7mil for my Divine wings, and it's 2.7mil that would have been spent on something anyway. It's like saying OMFG I spent 200ce heating my Armor, then half price elevators comes around.
Every paying player will rage at first, Cos their 3mil wings are now cheap as Colour changes (Does anybody care about those anymore?).
But, like a friend said to me, sh'appens, everything becomes cheap at some point, in 2 weeks the promo will end, and people will be selling them for days, till they go back up to price. Till then, featured auctions will be all about the doggy tails and prismatics.
TL;DR Deal with it.
I'd love to see some P2Per comments on this, or anyone that spent a small fortune on featured wings back when.
I always wait until the period stops giving that item to sell it. Then I wait until what I think is halfway between the promo giving the item and the next promo, because it is essentially a "drought" of that item.
I learnt this strategy from GraalOnline. In one server, at halloween they had "Rare Candy" (pokemon reference?) that dropped from enemies. They were rather valuable, and during the time you could get them, they sold for about 50k each, which took about ten minutes to earn, but in the "drought" period, they sold for about half a million.
