My personal experience is a bit divided:

1.) Cursed Soul: old/new frequency is very nice. I like it a lot.
2.) Disruptor: Too slow for my opinion. The little break between each burst is too long. It should be more like NC2.1
3.) Slasher: Same as Disruptor
4.) First Love. Two Shot burst are not so nice for rifles. It should be like it was in NC2.1.
5.) Judge: Good as it is right now.

Did you have any experiences with other weapons?
