Sadly, some guilds with no buffs unlocked are claiming keeps in WvWvW. We have tons of buffs unlocked and we would happily share them with other guild’s keeps but right now we can’t.
So I would suggest those changes:
-The keep will get claimed by the guild which has the most member “capping” it (after killing the boss). They will get the big banner. However, if another guild comes to the keep and has more buffs unlocked, they can claim it too. If they claim it, a smaller banner will appear under the big one. People standing in it (and recognizing the banner) will think: “Ah, this keep is hold by <SWAG> with support from <the best> and <YOLO>”.
This gives guilds, which did the most work, the safety to claim the keep for themselves, but guilds with better buffs will still have the possibility to share them.
