In my mind I can hear how that conversation went with the Dev's involved with this :
Dev 5: Hey - DevMgr - I need to put some numbers to this Crystal Shard drop for LJ's... How about 1 in 50 trees?
DevMgr: No way, more.
Dev 5: Ok, how bout 1 in 100?
DevMgr: Nah, more.
Dev 5: Hmmm... 1 in 500?
DevMgr: *Remember's his fondness for PK'n LJ's in Fel*.... More.
Dev 5: Wow... 1 in 1000?
DevMgr: Just make it 1 in 12,000...
Dev 5: Holy crap sir, that's not rare - that's insane!
DevMgr: Yea... It is, isn't it... Muahahaha
Well, somebody had to decide.... When the cat's away, the mice... well, you get it...
