Atlas Memories

I really need to understand why most of the memories are the way they are as such a rare drop and end game experience. Outside of einhar memories none of them are worth running at a profit comparison to any alch and go strat because of the lack of atlas point addition, no league inside and in some cases just a terrible mod attached like all loot converts to harbinger currency when you'd have to run in my estimation 50ish memories of that type before you see a currency shard with hype around it. And strongbox memories completely bricked by your map choosing blacksmith,gem,artisan, strongboxes when it's a rare drop to see this memory why can't it be always fun to run like einhar memory of harvest beasts.
