Well this season, my diamond league guild made a deal where we basically "danced" with ALL the other guilds. The deal was, we would hold the inner 4 sectors for the entire season. No one else touches them, or they get driven back to their base. That way, we never had to rebuild siege camps on those provinces. Then we flipped the second ring of provinces with all the other guilds, back and forth all season.
I personally love the farming... cheap FPs, diamonds, etc.... but I do think it is bad for the game.
I know that for every 100 battles I do, some whale is doing 1,000 battles, and for every 100 FPs I get, they are getting 1,000.
Unfortunately, GbG has turned into a rich-get-richer feature.
