Quests are not training or cakewalks. Anyone who thinks they are is wrong. Training a skill is just having patience to watch the same animation thousands of times. A quest actually requires a degree of mental capacity. A good hard quest is not "i'll watch several thousand cuts of a hatchet/ pick/ harpoon etc.," its "okay, i just spent 2 hours trying to guess who to talk to next for this balad (god i hated that)." For the most part, quests are much more fulfilling without guides. Lets also not forget that quests depend on levels, so some interference is necessary. Bottom line: they are separate acheivements, and uncompareable.
