Most of the information in this guide is irrelevant if you don't have the right gamer profile. For example, if you're a casual player, you may not be interested in farming tactics or strategies, while collector profile will need all of the information to allow him/her to collect all of the new characters.
This guide is not intended to be read as a novel. Pick out what you need and come back to it when you are ready for something new. Keep in mind that we all go through different phases in the game and it's not necessary to know everything until your role has evolved.
