Tired of the same theme playing in the guild halls? How about a purchasable guild hall jukebox? You can buy it (say 600k CR?) and than buy separate tracks for a lesser amount (how about 30k CR?). And it can play client-side so we don't have to fight over it. Would make the guild halls a bit more flavorful to visit.
Weren't there like, three threads about the exact same thing?
Also, it has been added to here: http://forums.spiralknights.com/en/node/68467
Which is the new place to discuss more recent Guild Related suggestions created by the guy who compiled the last megathread the latest Guild update was more or less based off.
Also he knows what he's talking about.
