Eidson also notes some major 'under-the-hood' revamps. The way a beast's happiness worked was arcane and hard to understand, both from a player perspective and in the code. Beast happiness has been refactored, with the end result being that beasts can be made happier, more easily. From the player perspective, this will result in beasts doing more damage and earning experience more quickly - a much requested feature. Additionally beasts can now be stuffed, their movements should be more in-line with player expectations, and eggs and enzymes are more informatively named. An interesting look behind the scenes - expect Game Update 5 on the live servers soon!
