The Scarab Occult Terminators with the Soulreaper cannon and missiles are very broken. The missiles are ridiculous, they can spam them one after the other(I've had them spam as many as 6 in a row) and you can't do anything to avoid them. They home in on you, go around cover and are in such a wide spread that they are basically can't be dodged. They can also fire them without even being able to see you and they just land on your head. This is not balanced in anyway shape or form. Combined with the fact when they spawn they bring more majoris with them just compounds the issue. 


My recommendation is to significantly reduce the amount of times they can use their missiles by making them have a long cooldown. Further make it so you they don't have such accurate homing. You should be able to use cover to your advantage to avoid them. I recently encountered them where I get hit with 3 consecutive volley's from a terminator who is not only across the map but can't even be seen. This is not good enemy balance
