If they can split the taming between having a mount and using one as a pack mule i'd be for it. we don't need mounts, i'd hate to see this turn into ARK.
but if we could do something like a carrot on a stick (or in this case hotdog piece on a stick) for the worker ants to help haul things for us, that would be cool
I don't see any need for flying, the dandelion fluff is fine for slowing falling
Agree with @01d Guy they want us to build traps and such. I'd rather see ropes included and a hanging net to keep the ants out.
no need for high tech, a basic filtration system, again like @01d Guy mentioned, would do just as well if not better. To expand on his idea, you could make a funnel with plant fibers and woven fiber, fill with sand and charcoal and a piece of plant fiber to filter the mud puddle and such water right into your grub canteen. Limited use, maybe 6 or 8 times before it "breaks", breaking meaning the sand and charcoal is gunked up to much to work anymore.
Sand would be found in various locations in the map, and charcoal from the cooking spit.
