A few ideas:
1 - when an enemy guild declares war on you and their name is listed in the "received" declarations tab of the War Status section of Guild menu, make this more interactive. Allow players to right-click the guild name in this spot to bring up a context menu with options. One option could be "return declaration of war" and one option could be "open guild info page." Currently, you get a declaration against you and you've gotta go type up the guild name in the ranking window to search for details on who they are, and to declare war back you have to type the name too. More options in this area help make things more convenient with less additional menus to jump to.
2 - track individual player kills/deaths during guild war. This feature does exist for nodewar, but not for GvG. I'd like to be able to dive into the war and see more details of which members contributed to the overall warscore.
This seems like a pretty good idea. It would allow guilds to see who is feeding the warscore as well, if someone is routinely going 2 and 60, the leadership can tell them they need to stay out of wars in the future. War scores can easily be falsely inflated by just one or two people who make the whole guild look bad, which could affect a guild's abilities to make alliances. It also makes it alot easier to return a dec and get the party started.
