With you, there was at least 14 of us. 
Some just don’t comment so often and they show up only to fill surveys and spreadsheets. What was average rating is hard to say as we don’t know all the opinions.
About AI thing… It is not that improving some parts of AI isn’t impossible, some things probably could be done easily and quickly. But they still would need to take time to identify these areas, and then implement them while not screwing AI decision tree. I suppose this is delicate matter, and when there in this decision tree are calculations responsible for getting chance of hitting each target in a range and chance of being hit by each target in the range… whole process of calculation still may take a lot of time. Probably because each unit has to recalculate these things several times based on the available actions. Adding there something - can be a ticking bomb. 
I’m currenly learning the development, so I can’t say anything for the Snapshot, but… AI is probably one of the last things I would try to touch while fixing the game. Game content is still not finished, and each new addition can screw things up.
