Guild Wars 2

One thing that could be easily implemented is (at least I think so), is commander chat. Simply a chat that works similarly to party chat, but applies to the entire zone, a zone-wide /say. Although most commanders are on comms, it would greatly benefit the pugs running along, who don’t always read chat during combat, and could benefit from seeing orders on-screen.

this would be cool. They should just do custom chat channels like in WoW.
