So, I was reading pages on the developer wiki and found 2 things about niches I thought might be applied to miches. First, on the actual Niches page, they listed generalist and specialist separately. This more or less matches my earlier suggestion here to fix @thriveuser1454’s complaint. Additionally, Biomes suggests having SIZE based niches. This might help with both the rarity of a gargantuan cell big enough to engulf the player, and the fact that sometimes cells small enough to be engulfed all die off.
