So, Ancient Essence is the main bait for those randomly generated Diablo Vaults. However, it is a bit... Obsolete. It can be used to either upgrade unique weapons that many people don't like/use or terraform planets, which IS pretty funny, but then again, what's the point of terraforming, considering that the universe has the endless supply of all types of planets present in games. So, it would be cool if: - We could change planet's weather and gravity during terraforming as well as choose what animals will populate the planet. -It was possible to assemble our own weapons, much like the way the randomly generated, but with player control. -Create custom animals(?)
