Actually I know EXACTLY what that means. I was a Mythic employee and tested games as my job. How about you? This is alpha, and that doesn't change the fact that this was rolled out poorly. If you release a patch, you ensure that it works on ALL aspects of your product, not just the Servers you manage. I may be mistaken, but it almost seems like this was tested on a completely closed server, with a single tester logged in, and as soon as it was successful once, they included it in the patch.
If this had been thrown through the ringer, it would have(and might have, but just doesn't seem like it) gone through hundreds of tests where you try to break the server with tons of players logged in and an attempt to bog down the CPU usage.
Uh you paid for the full game and get to test it early as an extra bonus, if that's gonna get you this angry maybe you should consider treating this as a pre-order and waiting for final release. But in no way does this give you a free pass to be as rude to the development team as you want so please play nice. Besides, demanding further alpha testing be done before giving a patch to the alpha testers to test is rather silly lol, it's up to you guys to find mistakes they miss.
