I'd have to completely disagree. While it's not perfect feedback, it's been extremely helpful. They've helped me identify a lot of things that were awkward or just didn't work on my map. You have to remember, any feedback you get from anywhere has to be taken with a grain of salt, and 'silent' feedback (just the way that the players play the map) should be taken into account just as much as voiced feedback. Sifting through feedback is just as much of a skill to learn as mapping itself. Also, I feel like this goes both ways, give them feedback on what you want feedback on. Not everyone knows what it's like on the development side of a map, after all. I can't really argue that a large portion of the competitive community can be very hard to please, and some of them will complain about a map being bad when they refused to test it in it's development to make it better. Believe me, I share the frustrations there. But, I believe you're frustrations are being voiced in the wrong place, as Beater is actively encouraging competitive players to help test these map. He's brought valuable feedback that's hard to come by, seeing as there are only so many top level players to get feedback from in the first place. I feel like it's a bit of a shame that people in the mapping community would complain about their maps not being tested in the past, in a thread created by someone looking to bridge that gap.
