The cave quest isnt too hard with 5 if you got a healer with you. Just throw some AoE heals while you slowly click the seals with each toon, then move to the next one.

Shadow Wardens have only 2 stupid quests afaik. The egg one and even worse, the flower one where you have to collect 8 flowers from lava pools. Am not bothering with collection dailies, so I just skip them.
