Onslaught SoS boss is very not great

Onslaught boss is ridiculous. Given the fact that it's a 1.4M health Onslaught you would think there might be some nodes to help us but nope just some energy resist. So on top of the fact that it's an Onslaught with 1.4M health, you also can't punish any of his heavies or specials(cause he's Onslaught). In addition to this though, you can't reliably intercept him with your normal attacks since he LOVES light intercepting. They also made sure that you can't use your specials to intercept him either since every time you pass a bar of power there's a fun new power sting you need to intercept him to get rid of! Overall, he's been one of the most tedious and frustrating ones I've had to fight in this game so far.
