If you have questions about the game, please ask! There are many people here who would be happy to help 
There’s also a wealth of fansites, Discord servers, subreddits, video guides, Wikis, and the like all over the internet. It all depends on the nature of your enquiry. For example, if you had a question specifically related to how the mechanics of the Barbarian Rend build work, I’d direct you to the #barbarian forum, or if you were wondering how to gain more in-game pets, there’s a great guide for that too.
