We're experimenting, plain and simple. We're not forcing anything on you - this beta is something that was announced in General discussion, and is completely voluntary.
We believe that we can provide a platform for players to interact with one another that's better than we have today, and we're going to attempt to prove that. There are more things to consider than the posts themselves - things like changes in usage patterns, and polling the silent majority.
What we've released is just the start. We acknowledge that what you see is not a replacement for what you have, and the burden is on us to make the changes necessary to make the decision obvious to many. If that's not something that we can do then we'll have no problem admitting that we were wrong and changing direction.
Every change, (even potential change) is subject to backlash and that's something that we fully expected when revealing this effort - a level of controversy similar to when we removed denies, or announced that League of Legends would be free. Adaption takes time - both for the people who are interested to acclimate to change, and also for us to respond to thoughts and behaviors.
If you don't want to participate then that's fine - we understand. Choosing to make a post or two then never showing up again is something that will be reflected in the type of evaluation we're doing on the beta's success, and will be just as revealing and important as the two new discussions you've made in the last 30 minutes.
I think we do a lot of things that show how committed to creating great player experiences we are and you don't have to search hard to find examples. In exchange I think it's only fair that you give us the benefit of the doubt and allow us to conduct our experiment with a reasonable and rational approach.
If you want to provide pointed and constructive feedback then I want to have a pointed and constructive conversation with you.
