I appreciate the feedback and giving the map a fair shot :) nice to see. On one hand Im happy it got played, on the other im disappointed because i really do think that the way the pre season cups are ran are not a good environment for the map to be tested for league viability. I was watching some of the games and like you said, it was quite clear most people hadn't even bothered to look at the map before playing it which is going to skew the feedback pretty heavily.
The map has been one of the most tested in my group, and a large majority of the playtests I had on this map were extremely positive and hutty was in attendance for most of those. The simple fact is no map is ever fully league ready upon inaugural inclusion, The maps we have in rotation today started bad, and got a lot better over time though league feedback. Mist along with many of the other maps we have put a lot of work into testing are without a doubt more league ready than any other map that was added previously, absolutely no doubt in my mind about that. Snakewater, gully, process etc all those maps changed immensely through league play and were not considered very good when they first got added.
If you guys want the maps to improve and you want maps with active developers, the fact is you're going to have to just add the map and play it, no map is ever going to be perfect for league play when its added and frankly a lot of the current maps are not even close to perfect for the current meta of the game (along with none of those developers being around anymore to make changes)
