1. 2 pets are better than Camo Hunter or extra dots. Twilight Tormentor passively deals similar damage to Hurricane and you don't waste gcds on it. It also gives 2% wpd.
2. Crystal weapon is better than Rapid Strike because it gives 1k pen, sustain, 2% wpd and it's easier to weave.
3. In dungeons, sets with stacks are not the best idea because the fights are either very fast or dynamic and there is a risk of losing all the stacks, which will only reduce the damage relative to static sets. Medusa+Leviathan will provide us with good and stable damage, as well as Medusa gives us an additional slot for self-heal.
4. Poisons on the front bar are better than enchants.
5. 1 light pc of a monster set is better than medium because there is not enough pen in the dungeons on stam dd.
6. Lover is better than a Thief, because there is not enough penetration in the dungeons.
7. Fighting Finesse is better than Wrathful Strikes because you don't have a crit cap in the dungeons.
