Well, that is just because balance in terrible. You don’t see that in PoE or GD. You do see it in PoE2, but that is because their balance is also all over the place, despite all their experience.
Well, yes and no. On the one hand, it’s bad anyone that isn’t a top player doesn’t have a chance of getting one. On the other hand, that’s part of the incentive for the players that do go after them. Without a reward there’s no reason to actually try to kill them. And the amount of players that like a challenge without a reward is much smaller than the ones that like a challenge with one.
If you were to remove exclusive drops from Ubers then they would stop being content designed for the 1% and would become content designed for the 0.01% instead.
In PoE it works “fine” because the whole game is balanced around trade and SSF is an afterthought. Most people that use Uber drops never actually killed one. But LE has CoF and it’s an important part of the game, which complicates matters.
Ubers do need a good reward so players want to kill him. But maybe we can make that reward not be BiS items or build defining ones. Or maybe regular Aby has a chance to drop the same things but at 1% the rate?
This I disagree with, though. There are plenty of builds in PoE that aren’t Uber viable and they’re totally fine. That’s why you have mapper builds, delver builds, bosser builds, etc.
The problem in LE is simply that you don’t have enough content yet to justify that specialization. Everything still revolves around doing mono echoes over and over again forever and ever. Even people that want to focus on killing Uby still have to do mono echoes over and over again forever and ever.
And the fact that the best way to farm Uby is to imprint his woven echo makes this even worse because monos are character locked, so you can’t even create a “mapper” to farm Uby resources and switch to your “bosser” character to fight him.
And, again, there’s the issue of PoE being trade-centric and LE moving away from that. It introduces new difficulties that also need to be adressed in this regard. In PoE you’re not expected to get everything yourself, you’re supposed to buy the stuff you aren’t able to get yourself. In LE, half the players are CoF and simply don’t have access to what they can’t get themselves.
