GUILD WARS
And I'm not talking about the ArenaNet game of the same name. I mean declaring war on other guilds. In other great pvp games like Age of Conan and Darkfall, my greatest memories are of fighting in wars/skirmishes against enemy guilds. There would need to be a new zone, but only large enough to fit a single keep. Think about it, a guild hall that is there for more than just crafting stations. Guild resources going into repairs and upgrades rather than just being hoarded in gbanks. An opt-in flag system so that PvE guilds can stay out of it. A kill on sight event where once per day you can hunt down enemies all over the world map.
People are far more likely to stand up for their close-knit guild than for their arbitrary lore alliance. There is history and friendship and pride in fighting for your guild. Choosing champions to lead or to represent in duels. Grudges, friendships, drama. Going on group patrols, stealing resources, sabotage, infiltration. There's no end to the replayability here, and it's a step away from the monotony of AvA. And the implementation would be relatively simple, no new resources needed.
If they had a system not only would I sub up again, I would be way more active in guild events. The current guild system is nice but lacks a certain something. The same can be said about PvP.
What do you guys think?
