I'm not quite sure where to put this, so I'll put it here.
In my opinion, the guide was well written in some aspects, in others, not. The guide looked mostly like stolen forum posts, and some of the material was grossly out of date.
For example, the author changes the spelling of some words and occasionally even the grammar is poor.
The complete 'guide' leaves many promised things unrequited. Many of the ways mentioned to defeat every class in PvP, earn gold easily, and so on were merely few vague bullet points that did not provide much help.
As a matter of fact, some seemed common sense. But as an example of an out-of-date issue, the hunter 'dead zone' is called to the stand. The so-called 'dead zone' was before patch 2.3, which was quite a while ago, despite the guide being 'frequently updated'. The dead zone occurred when the hunter was crowd controlled and the opposing class stayed between five and eight yards (the hunters' range for melee and ranged attacks), where the hunter could not hit them.
Even worse is when telling 'how to beat other classes, the guide does not organize such for specialized druids. (E.g. Feral, Balance, Restoration.) This can get very annoying at times, such as to beat a warrior, you have to 'put bleeds on him'. This does not seem very considerate of the author towards Balance and Restoration druids, as they do not often use feral forms.
Another thing to bring up is the raiding walkthroughs for pre-Burning Crusade raiding bosses, which have become obsolete since.
The talent builds were good, other than some the same as others...
The gold guide for druids was sub-par. It said basically to merely get two gathering professions and sell stacks, and it also told of one or two vendor locations.
Now, all in all, this guide is not a very good one. I could go on further about it, but my hands are tired of typing, so I'm going to wrap this up. This guide seemed poor in many senses and I would give it a four out of ten. Many of the things seemed common sense.
