Imo guides are not necessity to have, they are good to use only after you beat the game or get stuck, finding things by yourself is much more rewarding for gaming experience.
There is a guide for Divinity 2 if you still wish to use it though.
http://guides.gamepressure.com/divinityiiegodraconis/Yes i do agree, however no matter how thorough we try to be, we're all only human we can't find everything, not without the guide.
Let's face it, none of us would have done and found all there is to do in Oblivion or Fallout 3 without the guides.
