The Guide is pretty basic.
The advice given could be summarized into three things,
- use the catapults
- camp the king
- perhaps get a trapper
That does to mean it is a bad guide. It is absolutely on point.
But it does not help those who cannot finish TH Keep.
1.) It is not about you, it is about all
It does not help if you have a clue how to do it if the others do what they want - and do it wrong.
2.) The ability to work as a team is it what makes TH easy or terribly hard.
That is the crucial point. Players must agree on someone who leads and on a strategy. People fail TH because they do not cooperate.
And no guide, not even one written by God himself, can make your PUG smarter... get a guild or group who plays together on a regular basis and you can forget about the guide.
Get a PUG, and basically you can start praying...
