Gate creation was one of the best features to arcade. Allowing us to influence what kind of levels generated in each stratum. Not only that but it consistently used our minerals. Right now, moonstone and valestone have no uses, just 2 items filling up in my inventory. I've been hoping this feature comes back which is why I'm still stocking up on them. Bringing back gate creation will also get players more engaged with the game, since every gate wouldn't be completely rng.
