Terrible Performance and Design Choices

Why does every rare monster have a set of ridiculous mods like temp bubble, mana siphon and haste aura? Why does everything slow you down or stun you in this league even when you're wearing the right charms and gear and have good skill tree? Why does my game stutter every few seconds? Why is temple still not worth running in endgame?

And good luck crafting in this league. Crafting is back to RNG gambling unless you're a streamer who can play 12hrs a day. Since they removed homog omen, good luck buying catalysts or omens to craft. Price of reaver catalysts and anything else useful for crafting is super expensive now. Good luck running juiced T15s or pinnacle content when the game crashes every 2mins to get the currency you need to "craft" or upgrade your gear to farm even more.

Only things worth running are rare tablets with effectiveness and rare/monsters. Breach and abyss are still good but again, homog omen is gone so... Temple is not fun or rewarding. Delirium is whatever, ritual is okay. But the performance of the game is still terrible after GGG promised us they would improve performance, so running juiced maps still causes the game to stutter and slow down quite a bit, especially if you're playing with other people. I can't tell you how many times I've died in .4 just because the performance of the game is terrible. Usually I push my main toon to level 96+ but in this league I have no interest in playing, it feels like a chore.

I've had more disconnections and bugs in this league than in all other leagues combined. Why is the endgame performance still so terrible? Why is the endgame still not finished when GGG promised .4 would be endgame overhaul? Why are many of the endgame mechanics still not fun?

Bad league mechanic, bad performance, less crafting options, etc. One good thing about this league is the Druid class, but with the exception of Druid, .4 is the same as all the other leagues except overall a bit worse. A couple good buffs to ascendancies and gear, but overall it seems like more nerfs than buffs. Why did GGG think this was a good league to release?
