Trying to do this on an alt, but it’s really overtuned.
As an elemental shaman, and freshly 120, the first mobs to kill were already almost impossible. Even after equiping 385 nazjatar, it wasn’t easy.
next fight with the big armor is even worst. I know there is a big button that can avoid some of the attacks, but the thing just hit to strong and has too much HP.
I don’t say everything should be easy, but this might be a little too hard.
Did it yesterday on my goblin and yeah. This questline is way to overtuned. That fight you mention is doable but you’re not allow to make any mistakes and also you can’t take him down too fast and too slow because that might result in getting explosion right after or right before a flame thrower. If this happens you can’t do anything, you will just die becaue you can’t use your shield twice in the row, it has a cooldown.
Another thing is that last scenario is bit buggy. First time I did I couldn’t defeat Gallywix becasue special button didn’t show up so he just healed up everytime. After reseting it I was able to kill him but I had no good way of avoiding the Flame Thrower so it’s easy to die.
It all should be looked at. Not everything should be easy but this is the only heritage questline that is punishes you hard for mistakes.
