What i think the op is trying to say is that
1) yoshi has no plans of changing the atma drop rate in the future.
*perhaps 2.4
2) animus is still a grind cuz you still got that pesky 2000 myth cap
Which forces you to spend myth before you hit that cap and waste it unlike alexandrite which stacks to an infinite amount * so no pressure.
3) the animus fates can drive ppl mad with it\\'s low spawn rates which can gate ppl and force them to a halt from going on to the next book. * you can only have 1 book at a time. Thus causing ppl to spend myth they wanted to use for the future books.
