Hello everyone,
We have been showing you plenty of 7.3.5 previews of content that were in development over the last weeks. As we had said our Quality Assurance has been testing it nonstop to make sure it was polished as possible. The test realm will be open to everyone, starting April 13th, 2018 the realm will be fully open to everyone to help out and test. Testing is the best way we can get help from you, there is a difference between a small team of Quality Assurance testing and you, the community!
We need your help in filling in detailed reports, so we'll be making a guide for you here how to file a report on the bug tracker.
Visit the Bug Tracker on our Website.. Create a New Bug Report. Provide a Report Title, Language (English), Category, Realm, and Sub-Category. In the text box below provide the following information; Character Name (Name, Faction, Level, etc). Explain in detail the bug you have found (where did the bug happen, what phase was the bug in, etc). Please provide full details, especially if it’s a bug with a spell mechanic. Explain to us how to reproduce this bug. Evidence (provide us some evidence, screenshots and YouTube videos are always a plus). We are aware that there is still issues, and our developers are working on every single issue, to make sure that the official release is amazing and wonderful to everyone! Down below are the list of features you will be able to test on the Public Test Realm;
