So when using bold, red, max sized text, caps and throwing a tantrum don't work, you're 'not heard'?
Well, "not heard" is something we can't know. Nobody on this Forum (other than the mods) has any idea how the actual processing of data feedback occurs at Inno. But I would say it's bad optics for them not to interact with their "test group" at all. They are, after all, in the service/entertainment business. Let's say you own a restaurant and plan to add a new item to your menu, but first you give the item to a test group to get their reaction. If half of them spit it out and run to rinse with mouthwash, it would be advisable to interact and ask why before you roll the item out to the general public. Or if you're a movie producer doing a test screening and a significant majority of your test audience walks out shaking their heads in disgust; again, it is advisable to ask why.
Of course Innogames, like the hypothetical restaurant owner and movie producer, is a private company and at the end of the day they can do whatever they want with their own product. I'm just saying that it's probably advisable to interact with your testers. To be clear, I am NOT talking about the live forums. I am only talking about this forum. The entire purpose of a test group is for the product designers and the test group to come up with the most profitable product possible. We (the consumers) and Inno (the service providers) are not enemies here. We both want the same thing, the best game experience possible, because that means the most fun for us and the most profit for them.
So yes, some form of dialogue in situations like this would be beneficial. I'm sure they can spare 5 minutes/day of one employee's time to interact with the people sampling their latest product before the public rollout. Refusing to do so defeats the whole purpose of having a test group in the first place. It's just my opinion though.
