No no soul purpose of testing NA/EU would be like this event for example ncwest had the patch on there internal test server yes, so 100 or 200 random players picked those players will be perm testers for patch content before it is pushed to our live servers see where i am coming from.
We already know what is coming due week before live stream ect just makes more sense to be honest, economy would not be touched by this.
I use to be a tester on Archage before stuff went to live servers you know was handy seeing if patch was fine or not.
