I don't fly WW because winging isn't within the spirit of the event. There's no way I'm shooting at a Mongrel if there's another target to shoot at. It's not fair to the other participants, so I don't attend. Those who feel similar, should do the same, IMO.
Since you're working on the honor system anyways, why not ask everyone to fly in plane only icon mode with squad highlighting and wingman highlighting off. It'd be nice if you could force those settings in the arena tables, but I know the CMs can't. Anyways, I think if everyone flew with that icon setup, it'd remove the planned wingman problems.
