A year late and ya'll are liars. "We're never doing Guild Halls on Kaladim" Everyone stops playing Quick, put in guild halls!! "swear word" you guys.
I highly doubt the reason "everyone" stopped playing was because of a lack of guild halls. Hell, it probably wasn't even in the top 3 reasons for most people who quit.
I don't like the guild halls, completely drained the city. No I wasn't chatting it up and role playing with random afk botters at the broker... but when the city is empty and no one talks in chat game feels dead.
