As Massively's Anatoli Ingram discussed in his Flameseeker Chronicles column yesterday, Guild Wars 2's September feature pack will include significant changes to the commander system that marks player volunteers as leaders on various world maps.
After the patch, commander tags will become account-bound rather than character-bound, meaning your newbie Asura can strut around Metrica Province as if she owns the place. Consequently, tags will triple in price to 300 gold. Players will also be able to customize their icons with spiffy new colors intended to "facilitate a range of tactical uses" like organizing groups in PvE and PvP.
Already a commander? Lucky you: ArenaNet says you'll be grandfathered into the new system for no extra fee. The studio plans to consider "possibilities for recognizing experienced and prestigious commanders" in the future.
