Hehe Just kidding, keep writing if you have to do it personally. But seriously, most of them are practically pointless since they are literally a run down of a wowhead transcript. 99% of guides:
1. "Here is what garrisons are" (if you wanted to know that, you can read blizzard texts)
2. "Here is what buildings do" (wowhead information, or ingame information)
3. "This is what some important abilities are" (wowhead information rehash).
It might be more interesting to get guides that actually have strategies, rather than the same old wowhead/blizzard or ingame info.
