The quote is too messy.
You got the single phrases and cut them out of their context.
The grind is something very long and, for most players, boring. The grind is, by definition, something you don't like doing, that leads to a very good reward.
You can't ask for equality in an RNG-based grind, it's stupid.
Accept it, or don't do it, because atma grinding is not "for the skin", but for the animus: it's like saying that Hydra and Chimera are useless because I spent more time doing Ifrit-Garuda-Titan than them. You don't do animus by completing 9 books, you do it by completing A relic reborn, then grinding 12 atmas, then completing 9 books. You didn't spend more time grinding atmas than doing animus, because you were doing animus all along.

I explained this, twice, with examples.
But I know you won't bother scrolling up so here we go again:
If you roll 3 dices one every 10 minutes, you can get one reward at 10min, 1 at 20 min, 1 at 30 min, or none; if you roll 3 dices together after 10 minutes, you can get one at 10 minutes, or none.
The number of FATEs changes the overall drop rate, the time it takes to you to do them changes the time it takes to actually drop.
If doing 1 FATE every 10 minutes you drop after 15 FATEs, it takes 150 minutes. If you're doing 3 every 10 minutes, you drop after 50 minutes. It's like rolling a dice to get 6 (but not getting it) then waiting 10 minutes, or rolling continuously until you get that 6, it takes way less to go faster.
