I had trouble to my first rogue i made on eternal. Learned how to build this one i made for season and I just destroyed the WT4 capstone boss in like 30 seconds at level 57. just stood there and face-tanked him. My problem at first was not focusing on defense enough and using gear with wasted stats.
Next best thing I did was running cold imbue. I always thought it seemed bad compared to others but im absolutely ripping stuff with it. Can’t get hit it the enemy is frozen. Pair that with Pentinent Greaves and cold damage talents and you smash bosses bc of the amount of stagger you produce.
