One of the new features to be added to Mytheon is the Group Finding Tool. This helps facilitate you finding a group to join up with and get to business. The tool will help you find just the right group to take down that one monster or boss that will get you the bragging rights.
Secondly, The Dungeon Finder has also been added. This is a way to help you find dungeons and navigate them. It is designed to help you play more effectively as well as joining instances at different times and various entry points.
Of course, as many of you will be new to Mytheon with the Open Beta starting, they have also improved the tutorial. It provides you with an in-depth introduction to the basic elements of the game and sets you up to learn the more complex elements later on. Right now, you can log in and start experiencing the gameplay of Mytheon for yourself and all of these new features.
