About league mechanics and the loot quality

Yo guys can we talk about the "Balance" changes that GGG made for this league? I mean Abyss was strong, Alva was an excellent farm and those mechanics got nerfed quite a lot. I do believe some balancing was necessary but those farms are nearly dead now. I'm rolling 170 currency 120 scarab 120 quantity maps and getting out with 1 valdo box most of the time... And the more disturbing thing is a lot of people thinks that GGG shadow nerfing mechanics (without announcing the changes). I believe in that too. Think about Alva farming, lots of high-end players did that and got multiple mirrors from it. Then the loot quality dropped like hell after a patch that not relevant with Alva. I was trying to make a build for that farm and the day I've completed it they announced a patch and I have wasted my days making this build, getting the currency needed for it etc. Same for the abyss! I made my character and then boom, nerfed.

All I want to say is being fair and not to over-nerf those mechanics. Being transperent about the changes and to the players. Are you guys scared from your players to have fun and getting some good loot? At least announce it...

Thanks for your time guys. Someone had to talk about it...

Even with 1000% increased everything rng is still rng.
I had a 50m shipment return with no shards, so shit happens.
