No, not at all. All of our content, articles, guides and other features are completely free for public use on the website. We do not want to penalise people who are not able to support the website financially. Simply by using the website and helping us spread the word about it, you are helping us grow.
However, there may be occasions where we gate certain products for paid members for testing and development. In particular, the Raid Optimiser and Team Builder will initially be released under a closed beta that will be available to Premium Members. Over time we will release features for general use as they are tested and refined.
