Here it is in a nutshell. If there are issues due to allowing the add-on creators within the system as it has been performed over the past 15+ years, Blizzard has to combat these issues.
Raise the subscription prices by a dollar - that’s right $1 - and that will pay for the additional security and people you necessary to monitor the 3rd party adds.
It makes no sense to omit the add-on creators, knowing that they help make the game more enjoyable.
This is my opinion but it would seem viable and nobody is going to complain about the extra dollar per month. This means $7 million per month for Blizzard. Make this make sense.
My left and right mouse tilt buttons are not recognized on the new mouse overs, I wanted to like the new WoW UI but the limitations are so high, this does not make sense to roll this UI out with the problems that are currently being experienced. This should have been perfected and rolled out as an option to start - develop it better and better, where people will want to migrate over to the WoW UI and then it will be smooth and invited.
