Blizzard has announced the addition of two new features to the Armory, the Arena Calculator which aides in arena related calculations (as the name implies), and the Browser Search Plug-in which allows players to search the Armory from anywhere using their browser of choice.
The Arena Calculator is a new tool that allows you to do a number of helpful calculations for when and how you can spend your arena points. You can calculate the number of arena points you'll receive each week based on your team's rating, and you can calculate exactly how long it will take you to earn enough points to purchase an item you want. Choose one of the three useful calculators to help you answer the following questions:
- How many arena points will I earn this week?
- What's the average rating I'll need to get my desired arena reward?
- When can I expect to get my desired arena reward?
For your convenience, if you have a profile pinned, many of the fields in the calculator will be automatically populated with your current arena statistics (Opera and Safari currently not supported).
