Bonechewer was a pain for me, but the gear for the quest is great. I think i still have it on my toons now at 69. The good thing with bonechewer is that once you get your 8 (i think it is 8) you cannot pick anymore up, but in boiling you can just pick it up no matter how much you have. This is a huge problem for me because i have auto loot on so my main will always get collection quests first, but if there is no limit then i usually skip that quest. Once i was done with that area i had about 100 blood on my main, you should be able to trade collection quest items.

With drop rates the same thing always happens to me. Lets say it is a get 8 blood. First 10 mobs nothing, next 32 mobs 100% drop rate, next 100 mobs nothing, and then every 20th mob i get a blood. Half the time i am like screw that one toon, but i wanted to keep them all the same lvl, it is just fun to see everyone lvl at once when you kill a mob. Now that i am lvl 69 it really doesn't matter as much. About 1/3 done with the lvl and only have 6 bars that are not rest (well as of last night, when i log tonight i will only have about 3 bars not rested, which quests will make up for. I love that last lvl grind, it is usually always 200%).
