I don’t mind the fact that you cannot use waypoints when your party members are in combat, but some bosses are extremely difficult now due to this. I was playing Crucible of Eternity earlier which we ending up abandoning the run due to the difficulty of Subject Alpha – part 2 on path 2 after countless attempts. I can’t imagine how difficult the explorable mode in Arah will be.
People who only run pick-up groups are going to suffer with dungeons terribly.
I think they should forbid waypoints in a new hard difficulty or something similar, which has increased drops/rewards for the more elite players whilst keeping the original difficulty in a normal mode.
I completely agree with you with the loot update, but I think this was done to help people who farm just to leave masses of unlooted corpses with common items located on them. Still a pretty unnecessary update.
The bug in dungeons allowing people to kill certain bosses effortlessly was definitely needed.
