In GW there is alot of people that do GvG (guild vs guild) and PvP. The only thing I saw was for WoW pvp that includes a KoS. But in GW there is no KoS. I know the members of my site would love to have something less confusing then the one that is out there. I was thinking that it would be a good idea for the GW gamers to have it's own GvG/PvP addon. All it would need is a way to list who is one the different teams in the case of the gvg and the different classes that are offered in GW.
We would like to be able to do more automation with PvP/RvR, but at the moment Guild Wars/GW2 doesn’t allow addons (to my knowledge) and haven’t opened up the API to let third parties do this.
