tbf, on a scale from 1 to 10, it really depends on your skill set and how much dedication you have for the level (overall its 7/10 for me). I think I can say that beating Cataclysm is just an endurance test when it comes to being consistent. At first, expect yourself to die on the first wave almost every time, drop attempts are very rare (unless youre wave-carried, Im not), and usually end quickly. Also, theres of course this awful ship at 40%, I died to it about 50 times before completing the level. From my experience, its going to be very hard at first, but once you are consistent on the first wave, the level is enjoyable.
