@jazunia There is nothing like this. WoW is a game with a char level system like GW2, Rift and BDO. Here you don0t have a char level system and either a gear level system like Albion Online. The purpose of the knowledge system is that while doing tasks like Exploring/killing mobs/gathering/crafting and more, you will discover new abilities. Once unlocked you can study it to be able to use it.
More abilities = more builds
