Thanks for the summary! Since most teams wanted the "wood" fields for shooter calibration, we were always able to get on the formal fields with little wait. Also thanks to the FTAs for being patient with connection issues.
I would agree that more signage is required, especially between the queue and the fields. Volunteers would direct us to "Field 3" (for instance) when we asked for a wireless match. I couldn't see field numbers, and the volunteers pointed us in the direction of a 10 minute long lineup for a tethered field. I don't think they knew which was which either
I also like the idea of more informal testing areas. Teams that want to test mechanisms against defenses, or take shots against a goal don't need a full field - just some carpet and elements. You could fit a half dozen of these types of practice area.
