Its unlikely a spoiler site will be able to help people out to the degree we're used to. Perception is expected to be a MAJOR part of Vanguard and many of the things mentioned above will only be possible if you have the proper perception level and are traveling at the proper speed to find them. This is similarly true in combat. If you cant comprehend what the enemy is doing then you wont be able to learn from them. Also many quests will only be available to people with a certain diplomacy skill. So in general its going to be more involved than going to a spoiler site. You might be able to learn the last step you have to perform to get the skill but all the other pre-reqs might be entirely unknown.
