Some of the collections aren't as bad as they seem at first. There's a murloc quest in Borean Tundra where you kill orcas for 7 orca blubber, and it seems stupid and annoying like you would want to skip it, especially since it's not needed. However, the drop is 100% and they drop 2 half the time. I only had to kill about 23 orcas to complete this across 5 characters.
