Continuing Damage + Catastrophic = on average 3.5 hull hits, plus 1 system hit. Multiplier = 5.95
Extra Hull Damage + Catastrophic = on average 2.75 hull hits, plus 0.5 system hits. Multiplier = 10.5
So, for 57% of the cost, you're increasing average hull damage by 27% and system damage by 100%. Sounds like a deal to me...
Hmm...
Off the top o' my head, one problem is that the traits are all based on a comparison with a baseline weapon that does 0.5 hull hits per impact point. So, Catastrophic has a multiplier of x3.5, since its average number of hull hits is 1.75, and Extra Hull Damage has a multiplier of x3, since it does an average of 1.5.
But we don't account for the "layering" of these two traits -- the two together only increase the average number of hull hits by 175%, but increase cost by 950%.
Another potential issue is that Continuing Damage MAY be under-costed...
