I'm gonna explain how Primal fear would go for me and I'm asking this because mods on ASA feel so different including mods that's either copy Primal Fear or take a lot of inspiration for it.
On a primal fear, as soon as I spawn in I would find/make base the. Immediately get started on an egg farm. I'd basically skip to fabled/Omega tier.
I would probably tame something to help out in general at this point but to help advance, I would tame a fabled grifficorn and use it to dive attack a primal dino so I could get primal blood for celestial/demonic kibble.
Then I'd get a demonic and grind out primals and origins. To fight the emperor and empress, I would just power up my demonic tame and feed it health potions.
Then, to take on a chaos/spirit guardian. I would usually find a spot on the map where I can shoot the boss with demons attacks from a distance while the boss is stuck on something like the Ragnarok canyons or something. I'm sure I wasn't supposed to fight it this way. I know it's cheesing it. How did you guys fight it?
After one guardian I would tame a spirit/chaos take and kill the other guardian with it and after, I would wait until a chaos or spirit boss, always preferably a dragon, and then take on pikkon the creator and Nova the destroyer with the spirit/chaos tame.
This is where I usually stopped playing because I would always wait forever for a chaos dragon because it was a very rare spawn and most endgame tames were very rare and that always made it hard to keep playing.
That's it basically. It was very enjoyable to play primal fear but late game became a very boring waiting game. But back to theses ASA mods, I've noticed that you need a very good dino army to advance certain tier and I am not a big fan of making army's. It's just very tedious and annoying to me. I'd rather tame something very challenging but also powerful and then be able to take on new things with it. I'm just trying to see how other people think of this and how other people play these mods.
