...I expected a thread asking to remove ilvl synch and was prepared to explain why its in place and why we need it in certain dungeons.
I wasnt prepared for this nonsense...
OP, you, yourself even said that those dungeons arent actually really difficult even when done in the appropriate gear for that level - so whats the point in your idea even? When all a "proper" ilvl snych would do is to slow those runs down? Where is the fun in that?
A lower ilvl doesnt make a normal dungeon more difficult. It makes it take longer and no one is having fun with that.
So no, sorry - those dungeons never provided an actual challenge anyways (as you've admitted yourself), we dont make them take longer. (Besides: Thanks to nerfs the "original experience" is gone from many dungeons. And since I recently ended up in Amdapor Keep NM, I'd like to say: "Thank the Twelve!")
If you want a challenge for yourself because you consider that fun: you've got plenty of options for that, including running dungeons at minimum ilvl if thats whats fun to you.
For me - and a lot of other people, I assume - those dungeons are part of our daily farm-routine and while I'm intrested in challenging myself, I'd like that to be a challenge of skill and not patience because we're slugging through Sastasha NM or any other dungeon even slower than we already do.
