Actually in P2P flesh crawlers have decent drops, you get tons of fire runes(I sell to Tzharr store for Tokkul and buy furies, but it takes alot of fires), you can also get half keys, and I belive the tooth half is around 60k now, you also can get good herb drops aplenty, such as ranarr and snapdragon. They also drop nats so you can alch the silver bars that they drop.
