I am loving the mod so far. I would be very happy to see the option to either use a ritual to give a hive tyrant wings at the cost of biomass or have the flyrant be available for recruitment like the winged prime. Being able to easily access other dimensions with them would be quite interesting imo.

The foot Tyrant is already recruitable at higher tiers, unless something in the mod has recently broken. I plan to make a winged one eventually, it’s just a fair amount of work for a somewhat redundant unit, as-is.

I think right now, the faction really feels a lack of strong frontline bioforms, like the carnifex, screamer-killers, and norns, and it also doesn't have any major ranged options, like the exocrine or tyrannofex. Having a Neurotyrant as well would be quite nice, since it's a commander that wouldn't put itself in the front ranks and get killed for it, which is also something the nids currently lack.
