I find it strange that people don't always understand their role in something. This was an Alpha Stress Test. YES, feedback was welcome, but it was not mandatory, nor priority. To all naysayers, here's a clue:
Alpha Stress Test
Its not meant to balance the factions, its not meant to gather our opinions on the new mechanics. They are certainly open to them by their responses, but its an added bonus, not a first-on-the-list. Alpha testing is mainly to test server capacity, and gamebreaking bugs. That's gamebreaking bugs, not "shreks are too powerful". That only comes until Beta stages.
They gave us a chance to get a small piece of the experience in exchange. We have no rights to demand anything of them. Hell, for all we know, the actual updated build of the game was way more advanced, and the Alpha was an October/November version.
I suspect that community feedback is not gonna be a big issue for Relic anyway. Just based on what they plan for this game.
