Along the lines that Anet wanted us to have pride in our World(server)….Maybe a good way to make people feel more connected is a /emote based on each world servers name sake.
I have to make some kind of example to help some people visualize the end effect, not saying this will be pretty but here goes.
Upon entering a major drive to take a keep in WvW upon using the /battlecry if your home world was say Jade Quarry you might shout “Remember the Turtles!” (lol)
or lets say you are from Sanctum of Rall you might shout “Do it for Oldroar!”
As you and you comrades charge into battle!
Well I told you is wasn’t gonna be pretty. Well if you have a /battlecry for you home world that you think says it all then share.
