I love these suggestions. Tamable mobs are a hot commodity and is the only reason that Little Maid Mob is as popular as it is.
GoG3 on the other had has one thing LLM doesn't, Mob Diversity. Needs to be exploited BADLY!
But I'm running into an issue....namely with Morph.....
GoG mobs are now WORTHLESS with morph as they have no abilities.
This issue happened somewhere between V1.0.9 and v1.2.6 as back on 1.0.9, abilities in Morph still existed.
In addition to that, Biomes o' Plenty F's up A LOT of mob spawns via biome ID changes (Sphnix, Witch, and Kobold spawning in the nether)
