Ark is a terrible bad game and awful and runs like trash on every platform but one thing I wish I could have done when I was playing it is make my Dodo God Swarm where I have a legion of tiny but WAY OP'd Dodos that do ridiculous amounts of damage and are hard to hit because they're small as a base defense mechanism.
unfortunately taming, growing, breeding and levelling Dodos, as with EVERY creature in the game, is not only a ridiculously tiresome process, but also resource intensive and all your progress can be undone with one bastard with any kind of combat mount or a single missed step.
...and dodos are not exactly what you call... tanky...
