If i have understood this correctly, the new 1.3 multiplier for the JSP is only applied to the base damage.
For Gobi 48 * 1.3 = 62,4 , the difference in sneak attack critical for someone with better criticals would then be 28,8 ( 336 vs 364,8 )
Even with normal criticals 50 + % of the time the damage difference would be negilible compared to the huge drawback of having your weapons detereorate twice as fast ( btw it is CND * 2 now, right ? )
This would mean that unless you are using something like this machine, JSP and Juryrigging ( if you use it mainly for JSP ) is not really worth it anymore.
Have i got this right ? if so i need to convert all my JSP to standard 308 again *sigh*
