It is absolutely going to be possible to get all 21 within a day or two of season start. That’s part of what makes all of the drop rate complaints seem so off-base. These items are still very accessible, and even “very casual” players will be getting them and using them. Getting a “perfect” one will be difficult, yes, but getting a “usable” one will be relatively quick and easy. Getting a “perfect” ancient (let alone primal) weapon has never been easy.
I’m not sure why “3+ BiS item chances per hour” seems so insurmountable to you. Do you get 3 Ancient (whatever weapon your class uses) per hour currently? I’m going to guess probably not. A “good” Ethereal will probably be easier to obtain than the “good” Ancient weapon you’re replacing. For example, are you currently getting 3 Ancient Deathwishes per hour? 3 Ancient Little Rogues? 3 Ancient Dawns? Etc?
Most players play almost exclusively in Seasonal, and the items not carrying over to NS is absolutely no concern. Don’t believe this? Go look for public games in Seasonal versus Non-Seasonal. Non-Seasonal is absolutely dead, and has been for years.
It’s a seasonal mechanic. It’s temporary. If everyone didn’t quit when the 4th cube slot disappeared, they’re certainly not going to quit just because a weapon disappeared and they had to re-equip their old one.
This is such a ridiculous idea. Can you imagine how frustrating it would be if you had 2-12 ethereals dropping per rift (every 2-3 minutes)? It would be absolutely draining. Even just looking at the rolls to see which affixes it contained is already mentally exhausting and gets old very quick.
Go play PTR, open up five Bag of Fortunes, and tell me how much FUN it is to sit there and ID and examine each item. Hint: It’s zero. Zero fun.
The items being “rare” is what allows it to remain exciting and interesting when they do drop.
Should every item that drops be Primal, as well? Or can you acknowledge that rarity does, to some degree, increase excitement?
Getting an Ethereal while leveling will, indeed, be very rare. And even if you did get one while leveling, you would need to find another one to replace it with at max level. Literally none of your Best in Slot gear drops while leveling, and the leveling process takes most players between 1-4 hours on season start. “Chance to drop while leveling” is absolutely not a concern or consideration for the 3-4 month season mechanic.
I’ve never found a Primal Deathwish while leveling either, and I haven’t quit yet! ¯\_(ツ)_/¯
