Kara 5 is the best Dungeon/ raid in years. I felt that i was playing the true world of Warcraft creepy and filled of undeads from Warcraft 3.
The torch mechanic is like the old days of “fog of war” where you can’t see what is in front of you if you dont explore and its awesome.
About the dificulty, is a very hard Dungeon if you are not good geared and know what you are doing, this is how a normal mode should be for every Dungeon.
I just LOVE the slow paced Dungeons because they are hard and the lore is a 100.
