Hey guys,
Found a chart that lays out a ton of information regarding Garrisons in WoD, including buildings, their bonuses, and even recommendations for what you want your Garrison to do for you ultimately. i.e. there's a recommended Garrison layout for Gold Making or Raiding, etc. Hope this helps a bit!
