I'm not wanting to get into and argument about other peoples formations, if it looks like it works and players are happy, all is good

but
My comparison was more geared to the actual default_melee_state flag itself. If we were truly dealing with pure absolutes as it's relative to this flag, then by definition, how could it be possible that this flag excepts fictional code?
just to say it definitely will take fictional code eg: blah_blah that's the info I wrote up on the Wiki, that turns the skirmish and fire at will buttons off by default, so if your new discovery also does that you need to be very sure it's actually doing anything apart from making it use a default setting that must be in the code to override unrecognised commands. A lot of combined states gave that same effect; fire_at_will_and_engage_at_will however seemed to at least pass that test as the fire_at_will still toggled on correctly, but I didn't get any further being able to tell what effect it was having in game.
