After the last Chomper event, the horns were going for under 1 FSP. I know cause I bought a bunch up and resold for a few FSP weeks later. If you had the BP, there was a chance to stock up on them.
Also, you can make a good profit if you buy up linens for cheap or farm them yourself and hold them. Then at a later time sell them for big profits. So I really don't understand your frustration.
The horned chomper and Pharaohs will probably NEVER be released together again. it happened ONE time when the scarab epics came out.
I'm not frustrated, just providing my opinion/feedback on it.
-Again, most players don't/didn't have tons of bp to store horns, and probably dropped them after a while. So like I said, higher levels with alot of bp space have them stockpiled - which leaves a large area of players that wont even bother scavenging for the linens.
-From what I have heard (also experienced when it was last released in the caves) the drop rate is pretty low, so they aren't going to be cheap to buy/scavenge.
-Well they should (in the caves), as it would provide a bigger gold sink.
