Continuing the discussion from Rare Elites in Zaralek Caverns and Forbidden Reach:
We aren’t talking about instant satisfaction, it’s about time invested being AFK…which is different.
Example, you can log in now and do some attempt for Deathcharger’s Reins and then stop, rares that respawn every few hours are just being AFK until you do your daily attempt which sometimes won’t happend with your gameplay session and you consumed all your time waiting for your daily or weekly attempt. Besides that the attempt didn’t provide any progress because there’s not any sort of BLP like a currency drop for each attempt or as I mentioned before the attempt provided an increase % for the next attempt, similar to legendaries approach.
Shadowlands have some clear example of long term acquisition items but that doesn’t involve AFK time, example:
Predatory Plagueroc a mount drop from Gieger a construct that you can summon like a daily challenge, this one is pure RNG without any sort of BLP which could lead to an instant gratification for pure luck or years of grind but at least you can summon the encounter, do it 5mins of you gametime session and continue with your day.
