This is something that has really bothered me since PTOC. I believe that Event promoters have the right to determine what type of game they want to run. Now if you post it as an AP game...sure you must abide by the FPS rules. If it's not an AP sponsored game then who cares? But it seems like if you post something about FPS that is different than AP then people are out to lynch you.
AP sponsored/endorsed = Abide with AP FPS rules
Not an AP Event = Do what ever your insurance will allow you to do.
Seems too simple to me
