Welcome to club. I also did normal playthrough upto act2 Duriel defeated.
First issue i hope they just bump quantity massively too. I made a comparison test and it takes like 1200 Quantity to compare it to regular melee weapon to break. 1200 Quantity is like 500% buff, not 50% like they did.
Third issue made me bit laugh heh. Sure AI in D2 are idiots. God bless this idiotic AI times, before real world AI mess things up
