Blizzard needs to communicate better with its customers (that is what we are as we are paying for this product)
Whenever there are issues regarding exploitations, bugs and errors.... all we hear from Blizzard employees is that they are looking into it not much are being said afterwards or how they fixed it.
Maybe in the future you can address issues with what is currently being done about the situation, estimated time of when it will be fixed and a full report on actions taken and how to prevent this from happening again.
Example of issues:
*Ring of Valor crashes - it took Blizzard weeks to remove this arena. There were numerous post about this and no action was taken immediately.
*Current MMR exploit issue - Can you please address this issue as to if the players will get a permanent ban and will their achievements be taken away?
*Bots - you keep telling us to report suspected bots, how does the process work from when I press the report button? Maybe if you explain how the process works on your side, customers will have a better understanding.
For a listed company your communication to your customers is not so good.
Hope you can appreciate what I wrote here and find solutions.
