Especially with the latest Aylied ruin, having the ability to team up with 2-4 people (more people like a 12v12 mini war with siege would be fun too, but baby steps), and have a team battle in a arena that you have built yourself would really elevate this game. From a players perspective it would add a lot of fun with friends and guilds, from a business perspective you would sell more houses and crown furniture. From both perspectives it would add longevity and more elements to the game. PVPers would get more into housing. House decorators would probably go nuts making amazing arenas and battlegrounds. It would be a win for all of us.
