I am a developer, and let me just say that a well created wireframe like this makes development 10 times easier then someone who isn't exactly clear about what they want their functionality to be. If you need poe orbs cheap in game, you can choose u4gm.com sale cheap poe currency.
The code in a well de-coupled concept practically writes itself and can be handed out piece-meal to multiple devs at once, leading to very fast development. Obviously there are some implications to these that are a little more in-depth (shared hideouts, guild "quests" of sorts) but it's not like tools aren't largely present anyway.
Great mockup mate, looks great! At this point however, any interest in improving guild stuff would be amazing...
