DCOM, Thundercloud, xGenerate Health, and Primal Vengeance/ the other lost techs, (ect.). Item's that are all now belonging to a select few veteran players, or totally gone from Istaria. Most, if not all of these items definitely puts the few holders higher up on scale then the newer players in the community.
Now don't get me wrong here, I get the whole 'one time items' deal. But it's pretty sad to realize how much the newer players missed out, or to tell people "Sorry you can't have that anymore." I do not believe we would be upset if they didn’t come with an event. ;) All that I'm asking is to please have another chance to get these items.
-Coughs- ok so onto my idea for how these could be handed back out. ;p
(Very) Rare drops off higher leveled mobs. (Such as Kwellens, Beserkers, Nah'guk Ogres ect.) It would also suppress some of the boredom that’s been plaguing higher leveled players. There really is not really much of a reason to get up and go hunting just for the fun of it anymore. This would give us something to do, as well as possibly getting the items. (Limited time?)
Although I'm sure someone else could come up with a much better idea then that. :)
