While the interface is well thought out and has a very appealing look and feel, it lacks the customizability of the controls. The various actions for your character can be made into buttons to be placed on a ‘hot-bar’ or ‘quick-bar,’ however only one of these bars is visible at a time and as your character progresses the need for more hot-bars is evident. Thankfully there have been some third party interface modifications developed such as COSMOS (which includes a variety of excellent add-on tools) and GypsyMod. These are not necessities but definitely help. Blizzard has also been making modifications to the standard interface, addressing several issues, and plans to release these changes in their upcoming patch.
