Right now, the scaling of difficulty on Crucible is simply impossible to play.
At level 18 I was going into the Crucible to try to beat the boss, my build was OK, not super great, and I was still managing to hit the last boss every fifth to seventh run. Which is great, difficult, but most of the time I died because it was my fault, not even RNG. So I was compelled to try again and again to do better.
Now, at level 24/26 every little mob takes A LOT to kill, I have over 500 armor, over 50% resist on everything (using mesh armor and gloves), all items level 11 or more with sinergies. And still get stomped. Less than 5 hits from a common mob and I am dead. And the crucible is notorious for having swarms of enemies so its really easy to get hit constantly, also enemies that bodyblock, grab, push, etc.
I played at least 20 or more runs, and couldnt get past the 3rd map, my food stock is over and I already had to repair my armor 3 times because of that much dying. So back to grinding for food.
So now I dont feel really compelled to try the crucible because it feels like its not my fault, but its an artifical difficulty that is simply impossible to beat, or it will take so much time and luck that it doesnt feel like I did it myself, and got better, just got lucky with the echoes, for example the one that can kill enemies with a 10% chance per hit. When i get that i gets a little easier, but it just takes a single big mob to stagger me and I am 100% dead.
So is this a wanted feature? A simple stagger will kill you, in a 10 map, single life content? I belive that it shouldnt be at least.
