Here's a really nice build tool for The Secret World. It allows you to design builds out of game, and instantly swap to them while in game.
First, go to http://forums.thesecretworld.com/showthread.php?t=43386 and download Viper's Deck Manager. It allows you to save skill builds so you can easily switch without worrying about the limited default gear manager.
Second, go to http://www.drakkashi.com/secretworld/wheel.php and design a build. once you have one, click on the side to open up the deck panel, and click export. Copy the code for the deck manager.
Then in game, press control+v to paste the code into the deck manager mod under the import option. Voila... you now just imported a build without having to worry about manually placing your skills. You can then save the build to easily swap to later.
