While it's great to see IA Regionals will be occuring, FFG still hasn't released event rules for IA to begin with.
As an event organizer at a LGS, I can't really sell the owner on applying for the event without knowing the logistics it will entail.
Map set up and breakdown in this game can be time intensive and additionally a number of players have brought up the fact that they are not inclined to be pulling out map tiles in an event setting for fear of mixing up or losing them, as they are not something you can replace.
