I think a consideration to variety needs to be made for every piece of battle-related content available in the game. Meaning there is more than just one way to complete dungeons, primals, FATE's, etc. and what's required is acclimatization to the situation rather than a scripted route.

Let's take an example shall we? The second boss of AK for instance (which shall be un-named), the common strategy is to avoid the attacks, be in a safe position and to defeat the adds when they spawn. Yet an alternate strategy, based on the level/skill of your damage dealers, is to avoid the additional spawns and continue to damage the boss for a quick victory. A simplistic adjustment, but a different strategy nevertheless.

I don't doubt the usefulness of guides, but learning is what initiated the writing of the guides themselves. Let people think and flourish man, people will become better for it.
