What I like/liked about Warhammer was its open group concept--the public quests, the open warbands, and even the focus on RvR which made it seem like we were all part of one group, the realm. I had a sense of my individual contribution helping the war effort. But these keep upgrades will lead the game away from this, into the same old drama of guilds jockeying for dominance on a server. It's already happening though, with larger guilds creating closed warbands and taking keeps on their own, etc. Oh well.
