People emphasize kill quests (at the appropriate level) because they're easy.

Attempting content too high level for your characters is about as annoying as collection quests.

You don't have to limit yourself to kill quests. Rather than gouge your eyes out killing near-impossible mobs, why not gouge your eyes out doing a couple collection quests so you can actually earn some XP while you're at it?

Maybe some instances if you're opposed to collection quests? Not all collection quests have sucky drop rates.
