With the pending dissolution of world servers, the fundamental unit within WvW will become the guild (and perhaps that's appropriate in a game titled "Guild Wars 2"). As such, many guilds will likely want to run in WvW with just their guildmates. However, at the same time, they may want the visual focus a commander tag affords for any one of a number of strategic and tactical reasons. Unfortunately, with the current implentation of the commander icon, it broadcasts itself across the map.
This suggestion requests ArenaNet add a checkbox to the squad formation panel which will hide the commander's icon from general view, displaying only to the commander's guildmates. It in no way infringes upon the current commander icon mechanics; this is not a call for the creation of a guild-specific tag (though, perhaps, that's something worth considering, as well). Rather, everything remains as it currently exists including the requirement to purchase the commander icon. It simply asks for the addition of a checkbox to hide/unhide the icon from non-guild member view.
