I have been selling a combo of shards and scrolls. I don't have mongoose ( wish I did ) but have sold tons of savagery and exceptional stats.

The price for LPSs will go up in the future. People are changing trades or starting new ones, and its the cost of skilling up that makes old world mats go up like they do. Also, since most the outland enchants help to enchant level 35+ twinks, that will help make the price rise. Since people will be farming outlands mats less.

I have made over 3k farming the invasion spawns. I still have half the shards i got. Ill save them 8)
