It’s pretty bad. I decided to stick to it and go sapper 3 just to see what it’s like and man is it terrible. Basically only 1 useful skill for 3 circles.
Claymore setup is atrocious
Punji 3 second cast
Spike Shooter 1m 40s cd and is completely unreliable ( or maybe there’s a trick to having it actually hit the mobs you want)
Collar bomb only works about 50% of the time.
Stakes are incredibly tiny and pretty much just useful to pop it in melee range on top of a mob. Damage sucks too.
