I skipped those quests (running 1 shaman and 4 hunters ATM, all level 60) because I knew that before long I'd have upgrades to those trinkets and the time wasted wouldn't be worth it. If your intention is to level to 70 or 80 as fast as you can, quests like that not only slow you down, but by the time you're 70 or 80 you've got much better gear for those slots.
